It appears to be a rite of passage for a research operating system to develop a strange, non-functional and non-interoperating networking stack at some point in its life.  In entertainment, that would be called "jumping the shark" (quid google).

Don't do that.

Proxying IPC to a remote system may be a useful tool, but there are a number of dangers:

-- don't put things in the wrong layer (should the IPC layer be concerned with network addresses?  Application names?);
-- make sure you have a place to handle the leakiness of the abstraction (distributed systems are different from local access);
-- don't change everything in the abstraction you are "extending" (length, pointers, ...);
-- don't move to the wrong focus (is RIOT about distributed computing?).
