I expect to end up with a multi-level system, where you can use anything from
a DNS name (guaranteed to contain dots) through author IDs (no dots) to
blessed top-level names for universally acclaimed modules, for some definition
of universal.  Plus the technological fix of aliasing, as several of you have
discussed.  Basically, we name interfaces at a more abstract level than we
do implementations.  Devil in the details, as usual...
