This will import medusa and asyncore every time the ftp module is loaded, which 
seems a bit unnecessary.

More generally it seems a bit wasteful to define the server code in
the transport modules and so load it every time when we almost always
only want the client.  But you don't need to change that now.

+1 from me.
