As an aside: there are direct Ruby bindings into the underlying libsvn, so
it's possible to talk to a SVN repository directly (local or remote) without
spawning an external command.

Unfortunately libsvn doesn't seem to be well documented, especially for
remote access. A couple of interesting posts are here:
http://agylen.com/2006/07/14/using-the-ruby-bindings-for-subversion/
http://www.oneofthewolves.com/2007/03/06/ruby-subversion-bindings-finally-some-documentation/

So you're probably right to use the command-line interface.
