/srv just connects file descriptors. It doesn't have listen and announce. So unless you are posting 9P sessions to /srv (in which case the kernel takes care of multiplexing the many clients who open /srv/your-service), posting to /srv is dramatically less useful than announcing a network address: there's no way to keep clients separate.
9P is not a very good model for Venti. At best the 9P realization would be a single file /venti-rpc that clients could open and use to issue real RPCs. Russ
