Many lawyers who use PACER also rely heavily on the fact that it's updated almost immediately -- a project like this could never accomplish that, and could lead to malpractice if used in its place. For example, you can't sue people for certain things if they've declared bankruptcy, so you need a reliable, up-to-date way to verify they haven't (a common strategy is to wait until the last minute to file bankruptcy just to delay legal proceedings).
What's worse is that this project seems to be encouraging some kind of witch hunt:
> Now he wants to make "every U.S. Attorney and AUSA's full career as a prosecutor available to the public to examine in its entirety." So those are the links queued up in Project Asymptote.
That's how you want to honor Aaron? By using PACER and an army of volunteers to pursue someone's personal vendetta? I can't even begin to describe how tasteless that is; to take one of Aaron's projects and turn it into some kind of misguided inquisition, then call it a "poetic tribute to Aaron Swartz's memory".
If you really want to make court documents available to everyone for free, then do that. Don't use Aaron as an excuse to target US prosecutors.
