I imagine that something like that would go over well, but you never know. What I think would really do it would be RPMs of AOLserver and OpenACS. PostgreSQL already has a nice set of RPMs, and having the rest of the system ready to go would make it a snap.
I am still working on getting my OpenACS install working, and I've never made an RPM file, so I can't be of any help on this front at this time. I would like to change that, though.
