**1.** There is an unresolved problem with the SSL certificate, which I have fixed for the browser, but the command line tools (wget, svn) still don't recognize the certificate authority. If prompted it is "safe" to choose "accept permanently". Last I checked the certificate error created problems with some graphical clients (svnX) which don't know how to get past this prompt cleanly.
**2.** In-place relocate: I have done this myself with lots of uncommitted changes, and it works perfectly.
` cd cnmat`
` svn info`
... look for what is says under URL: should be something like svn+ssh://... copy that text.
