I'm not sure what you're getting at, Ben.

See below, please.

Well, I think my remark still stands. If it doesn't "require 1253 meg of
crap to run" today, it won't require it later either. All you need to do is
preserve the software version that works, together with the environment. I do
that all the time by putting it on its own hard disk. I boot from the drive
that runs the software. That way nothing changes. Backups protect that copy.
