dav-svn in multihost environments, but safe

Hello all,

i'm hav a multihost environment and i want to provide svn access for
arbitrary customers via dav_svn. is there a solution to have the
svn-directories of the users only available to the unix-users of the
customer instead to make them writable to the apache user (which
mod_dav_svn is using due to the fact that its an apache-module?

maybe it is possible to use cgi-access to svnserve to use suexec?

some other suggestions?

thanks in advance
ciao
ulf
