Implementing such a filesystem doesn't seem difficult at all.
libsmbclient contains all that is needed and we would only need to map
some samba structs to fuse structs. The only real problem that I see
is authentication. If we want to use this as a regular filesystem we
could mount one pipefs per connection (with authentication information
on connect) or provide login and domain information in the path itself
(doesn't sound like a good idea)
