/* The "real" RPC portmapper endpoints that I know of are:
*
* ncadg_ip_udp: 135
* ncacn_ip_tcp: 135
* ncacn_np: \\pipe\epmapper (?)
* ncalrpc: epmapper
*
* If the user's machine ran a DCE RPC daemon, it would
* probably be possible to connect to it, but there are many
* reasons not to, like:
* - the user probably does *not* run one, and probably
* shouldn't be forced to run one just for local COM
* - very few Unix systems use DCE RPC... if they run a RPC
* daemon at all, it's usually Sun RPC
* - DCE RPC registrations are persistent and saved on disk,
* while MS-RPC registrations are documented as non-persistent
* and stored only in RAM, and auto-destroyed when the process
* dies (something DCE RPC can't do)
*
* Of course, if the user *did* want to run a DCE RPC daemon anyway,
* there would be interoperability advantages, like the possibility
* of running a fully functional DCOM server using Wine...
