Well, we're not doing it to get around the GPL per se; we just want
to use use SMB as one of many transports for RPC. As it happens, most
of the requests serviced by our RPC server come in over TCP/IP (that's
ncacn_ip_tcp for the DCE geeks).

This sounds similar to the IBM patch Anthony mentioned, except they
may not have interfaced at the exact same place. We use filesystem
permissions to deal with the "security issues"; SAMBA, LDAP, the KDC,
our RPC server all form part of the TCB.
