    Nothing prevents you from running RAS server on both ends. If the RAS
client will try to dial - it will suspend the server's activity on its machine
for the time of the call.

    So, run 2 RAS servers, and have the dialing RAS client on either end.

    PPP is how TCP/IP is runned over serial. In Windows, PPP is RAS.
