Wasn't really thinking about Supreme Court filings, I was thinking the more mundane civil filings that happen day in and day out in say Santa Clara County Superior Court [1] where you can get a copy of all the documents filed in all the cases where the judge hasn't ordered the documents sealed.

I realize its kind of an odd thing to do, but you can go down to any US court house and just sit in the gallery and listen/watch. There are people who do this for Groklaw when they were following every bit of the SCO/Novell litigation.

The Novell/SCO case (and Groklaw for that matter) provide what I think would be a great service (when combined with copies of the original documents) so in the Novell/SCO case there were agreements about the assignment of copyright (or not) and how they were pleaded both by the defense and the prosecution. Reading how they were attacked and how they were defended gives tremendous insights into how such documents get litigated. Of course it costs time and money to have someone do that, but that (rather than just copying various public web sources for documents) would provide a real value proposition for someone who was trying to either come up with a document for this or wanted to know what questions/guidance they should give their attorney who is preparing such a document.
