Here is an excellent rundown of the legal filings and case law for the
Miller case, from beginning to end:

Eltacogrande: You said that no court has ever answered the question of "Is the RKBA a collective right, which would be exercised by the National Guard, or an individual right, like the right to free speech?"
In the literal sense, you are right. However, from a logical point of view, I think that this is incorrect.
Miller itself, by virtue of the fact that the Court heard the case and decided it on the merits, implied VERY strongly that Jack Miller, individual American citizen, had an individual 2A RKBA. Otherwise, the Court would simply have decided that the lower court had erred, owing to the fact that Jack Miller, individual American citizen, had no standing. The Court analyzed the history of the militia and stated that
In the absence of any evidence tending to show that possession or use of a "shotgun having a barrel of less than eighteen inches in length" at this time has some reasonable relationship to the preservation or efficiency of a well regulated militia, we cannot say that the Second Amendment guarantees the right to keep and bear such an instrument. Certainly it is not within judicial notice that this weapon is any part of the ordinary military equipment or that its use could contribute to the common defense. Aymette v. State, 2 Humphreys (Tenn.) 154, 158.
By doing so, by implying very strongly that
if there HAD been evidence that a short barreled shotgun had a "reasonable relationship to the preservation or efficiency of a well regulated militia," or "judicial notice" that such a weapon is "any part of the ordinary military equipment or that its use could contribute tot he common defense," then Jack Miller, individual American citizen, would have won the case and the NFA would be a mere footnote to history. (Of course, Miller was dead by then, so the decision wouldn't have done him any good). Had Justice McReynolds been informed that the US Army had purchased some 30,000 short barreled shotguns for use as "trench brooms" in WW1, maybe this case would've come out differently. I suspect that it would today if some poor soul was able to get his case about an AR-15 converted to a full auto before the Court, though the Court has studiously avoided hearing anything gun-related.
Of course, all hope may not be dead. Read the following to see something that Scalia said about guns, as well as some interesting comments:
