Actually, that is relatively easy. The Trac system which is written  
in Python and
can run under mod_python accesses Subversion. It doesn't have to loop
back requests to access Subversion through mod_dav_svn though, it just
uses the Python wrappers for Subversion to access the Subversion
repository direct from the file system. In both the case of  
mod_dav_svn and
the use of Python wrappers under mod_python, the user is that of Apache
and so they quite happily coexist as Subversion by nature has to support
multiple concurrent accesses to the file system repository.

The difficultly is only in understanding the API of the Python  
wrappers for
Subversion. For an example of Subversion access from Python see the code
for the following Trac plugin as an example, especially the  
code file in the tracrst directory.
