I think what Tridge means is actually 'forwarding' the RPC data (for
which Samba4 already has support, e.g. you can redirect a complete pipe
to a remote server) instead of having a hack that bypasses the local
endpoint and talks to a local pipe.

Yes, at the moment.

|  as ordinary users?
We haven't looked at that yet though we will need to in the future -
I've been working on some GUI utilities that need to talk to the local
smbd somehow - ncalrpc would fit in perfectly here.

Cheers,
