Two big warnings:
Upshot: The subversion client installed on the Solaris network is version 1.1.3, so it cannot read the new working copy format. (It'll talk to our server with no problems, though.) So, if you want a working copy in your Solaris home directory, make sure you don't use a newer client on it, otherwise it'll be unreadable by the default client. (This might come up if you mount your Solaris home directory on one of the College's Windows machines and use TortoiseSVN on that working directory, for example.)
So be careful.
