Thanks for the suggestion.

If I understand you correctly, given a URL of (say) svn.example2.com,
the SVN client would query the DNS SRV record for that domain to
obtain a port # (say, 3691) and target domain (say, example.net), then
send the svn request to example.net on port 3691, at which point the
svnserve on example.net would process the request.

In order for this to work, wouldn't a single svnserve have to listen
on multiple ports and have different roots associated with each? That
sounds like a good idea, but my cursory reading of svnserve/main.c
suggests that it doesn't do that currently, so perhaps I've
misunderstood, or perhaps this is just more of what needs to change in
order to implement your idea.
