Hey zwrighttm,
Unfortunately I gave up on this a little while back. Adobe released AUSST 3, which contained an executable binary that wouldn't run on my Linux hosts - and without access to the source code, there is no way to compile for Linux (that I can tell anyway).
I very briefly looked into using the Windows version and something like WINE, but in the end, I just run updates on my local Mac workstation which outputs to an NFS mounted folder locally served from one of our Linux/Apache hosts.
Not ideal, but workable!
Not so enamoured with AUSST as such (the downloading part), I constantly get exit error codes and mixed results... At least serving up local updates works well.
Anyway, hope that helps!
Cheers,
James
