Always good to see a new FOSS client in the wild - Particularly with
async support and smb1 abandonment :-)

So this means that the libsmb2 client code could also be used by the
cifs.ko kernel client? I think at the very least it'd be good to have
each of these projects using the Samba idl for network<->req/rsp struct
marshalling.
talloc/tevent usage would also be a nice to have IMO, so you don't end
up rewriting a generic event library, or hierarchical allocator
(libiscsi seems to have gone a little that way ;-).

I can't speak for others on the team, but I'd certainly be in favour of
hosting it under samba.org.
