DCE/RPC over SMB can be async in principal, but this has not been fixed
up in Samba4's implementation.  Of course, you could do this over TCP
directly.

DCE/RPC doesn't, to my knowledge, do server->client notifications very
well, but I'm not sure trans2 is much better...  

Even SMB signing has to make a special case for oplock breaks, the only
'normal' packet that is initiated server->client.

You could of course have an 'listen' operation, initiated from the
client, that the server may respond indefinitely to, without breaking
those semantics.
