9	There should be a transport table that is indexed by the transport name.
10	This table can be used to load/unload transports at run time.
11		OK. Table not writeable yet.
12
13	Then there can be a port table that is indexed by transport name and
14	port name. Plus a transport-specific table indexed by port name only.

16	The transport table could contain a column of type OID that points
