Time for me to weigh in, like I promised.
Alfred Edersheim makes a pretty compelling argument that the "sons of God" refers to the God-fearing descendents of Seth. This is how that argument progresses.
1. Under the assumption that the Biblical narrative is a history of the faith (which is one completely valid way of reading the Bible), the pre-Flood narrative is the history of the descendents of Seth, who were God-fearing.
1a. We are giving genealogies of the main line of Seth and the main line of Cain. Seth's genealogy emphasizes the good, while Cain's genealogy emphasizes the bad.
1b. Seth is born to replace Abel, indicating that Seth represents the church, while Cain represents the world.
This is one of those "Oh! Of course! How can I have
missed that?!" moments.

I am still not convinced that "sons of God"
clearly means "descendants of Seth" here, but this insight makes it seem (to me) far more likely.

2. The word "Nephilim" can be translated to something along the lines of "snatchers" and "murderers". Interestingly, the passage that reads "Nimrod was a mighty hunter before the Lord" uses the same "mighty" as in "mighty men", and the word for "hunter" is related to the word "Nephilim". In other words, Nimrod was a man-slayer. So, while "Nephilim" can be translated as "giants", it does make some sense to translate it as "murderers".
I don't know Hebrew (aside from a few words and phrases here and there), so I can't comment on this, other than to say "interesting, and supportive of this argument, if true."

3. Taking these two things together, this throws some light on why the Flood was necessary: not only did God's people mix with unbelievers, corrupting the faith, but the product of their union was a group of men so vile they were renowned for their murders.
OK, yes, that's certainly a valid reading.

Other things being equal (if they ever are ...

), yes. However, as the debate in this thread has shown, it is not at all clear that this is actually the simplest explanation.

However, the terminology of 'sons of God' isn't used elsewhere to refer to the descendants of Seth,
Not that this is even remotely conclusive, but Luke's genealogy of Jesus ends with "... the son of Seth, the son of Adam, the son of God."

and I really can't see any reason why that intermarrying would result in people that would be notably evil (in comparison to the descendants of Cain, anyway), or why they would be called mighty men or men of renown.
Sin and corruption are weakening tendencies; if the "descendants of Seth" view is correct, a child of a father from the line of Seth and a mother from the line of Cain would inherit the father's strength but inherit the lawlessness of the mother (or be taught it by her).

Further, keep in mind that the Nephilim are actually mentioned after the flood as well.
Really? I've seen that asserted a couple of times in the thread, but I can't recall ever encountering such a reference ... so ... verses?

Or at least people called the same thing, which would suggest that there was at least some connection, and they are specifically said to be giants. (The Anakim, who are also said to be Rephaim, which suggests that the Rephaim are also Nephilim.)
Now, admittedly I don't know the first few books of the Bible as well as I should, but that ("The Anakim ... are also said to be Rephaim which suggests that the Rephaim are also Nephilim") doesn't seem to follow.

Your comment about demons and bodies is interesting, but I don't think it answers all that much. Angels can have bodies,
And, as I've said repeatedly, this is not a given in the least.
Arien Mimetes wrote:
One last thing, in Jude 1:6, it mentions "angels who did not stay within their own position of authority, but left their proper dwelling". What exactly that means I'm not sure, but I've wondered if it's connected to the Nephilim.
At first glance that would seem to refer to the angels who followed Satan in his fall ...

One theory is that Nephilim is just a misspelling of necromancers and they were really just people who ran around making zombies.
Of course, not all theories have the slightest shred of plausibility ...

@Neil: I do have a question. How would the descendants of Seth be different from the descendants of Cain? They were both fallen humans, born into the curse of Adam. So what makes them different?
Tendencies toward specific patterns of behavior (sin or virtue) are often passed down within families. (The most obvious example in our own era is alcoholism.) So the descendants of Cain spent their strength in inventing new kinds of evil (a la Romans 1), while the line of Seth was preserved by following God.
