   Sure. Subversion either runs on port 80 when exposed
   as a WebDAV server, port 3690 when running "svnserve"
   or port 22 when accessed via ssh. Choose one that
   doesn't conflict.

   Subversion doesn't require installation in any
   particular place, so you shouldn't have too many
   conflicts on the filesystem either.

   Compared to Clearcase? Not at all. Subversion only
   compares to clearcase when you're using snapshot views,
   Subversion doesn't really have a dynamic view equivalent.
   In addition, Subversion only sends deltas (differences)
   over the wire for commit and update operations.
   Many operations can be done locally without contacting
   the server at all.

   Subversion memory requirements are not high, but I
   don't believe anyone has really done any measurements
   yet. It seems to be mostly affected by operating system
   caching ability (so, as usual, the more memory, the
   faster it'll be).

   If you use the "fsfs" backend, you can store a Subversion
   repository database on a remote volume just fine, so long
   as it supports POSIX locking.
   If you're on a Unix-style machine, just make sure it's
   mounted somewhere and that's it, nothing special.

   Naturally, I assume you realise that Clearcase load
   will affect Subversions performance?

   Make sure you read over http://www.svnbook.org/
