One way you can do this in the latest Interchange from CVS (or any nightly
build from April 10 or later) is to add two CGI parameters to any links
leaving the current catalog:

mv_force_session=1
mv_session_id=whatever

The catalog the user goes to will accept the session ID in the CGI 
parameter in preference to a cookie when mv_force_session is on.

This was added just for a merchant with a similar situation to yours.

If you're using an older Interchange and don't want to upgrade to a 
development version, you could apply the simple patch manually:
