Maybe it is a good approach to first setup the simpler svn server and afterwards, if need arises, enable access via WebDAV.
But does this topic mean that you want to use the SVN repo as a replacement to UVS repo? That would mean your quick fixes and improvements would only be available there at first until someone (I think Max) synchronizes it with SF repo?
Why don't you want to use the trunk path or another additional path within the SF repo?
