This actually makes sense: I've done similar things with OS image tarballs
in Linux, but always stored them as tarballs (which compress well), not as
disk images (which really, really, really do not compress well, especially
if they've been used for a while).

Subversion is the wrong tool for this, I think. The binaries are huge, and
there's no good facility in Subversion for discarding unwanted previous
revisions of a file or of alternatively named, copied files, so it'll clog
any reasonably sized repository pretty fast. I'd actually be inclined to
have a big backup drive and use something like "rsnapshot" to keep a few
backup copies stashed on a daily/weekly/monthly basis.
