We don't require SSL for anything. But I think it's a good idea to use it.

Some http proxies mangle WebDAV (i.e. Subversion) requests; by using https, we ensure proxies aren't able to interfere with the transmission; by recommending users use https, we avoid some support emails.

github serves all pages https; seems to work for them.
