These are two different mechanisms.  The former sends a message to the
_locally_ registered process RegProc at Node, and the latter sends a
message to the _globally_ registered process Regproc.  Note that the
same process can have a local name and/or a global name, and they need
not be the same.

In this case, the first mechanism might be a good candidate because
you'll have to know the node name in order to set up a connection to
the node.  When the connection has been set up, you can send pids
between the nodes.
