Environment variable to set the --tunel-user?

Hi there.

I'm currently setting up svn/trac for some users. Everyone but me should
be disallowed to login, but the project stuff will run with my non-root
personal account. Reading the FAQ I found the nice --tunnel-user option
for svnserve, but I'd love to use my key and be able to log in as before
and still change my username for svn.

To make my requirement more clear and since I don't trust my english
skills enough to be precise:

Current situation: My username on the machine is "dar":
I currently commit via svn+ssh and the logs know me as "dar"

I want to add some more "virtual" users, that get a restricted key for
my user account, let's call them bob and alice.

Future possible setup:
Subversion logs commits for "dar", "bob" and "alice", the latter 2 are
using the --tunnel-user option in the relevant line in my
authorized_keys2 file.

What I really want:
Subversion logs commits for "ben", "bob" and "alice", me being the one
called "ben" while still being served by my account "dar". I would like
to stick with one ssh key for me though, so I don't see a way to pass
the --tunnel-user option to svnserve without restricting my key to a
specific command. The only alternative I can think of is setting a magic
environment variable (via the environment definition for my own ssh key)
which is atomatically used as SVN username by svnserve. Does something
like that exist? Any other options, apart from using 2 keys?

Sorry for being overly extensive, but any help would be appreciated.

Regards,
Ben
