The inetd mode would seem to be the best way to handle this.  Then your
inetd or replacement can handle starting smbd.  Just watch out that
clients may keep a connection open for quite some time while not
actually using it. 

(I don't have personal experience with this setup, but wanted to give
you some hints about where to start).
