I'm guilty of not really considering an alternative (so many other things
I deal with more often). But yeah, now that I think of it, that is sort
This is a nice idea, and might even be nicer if it were taken a step
further and represented Erlang nodes according to a for-real URI scheme:
or something along those lines. There is probably some reason the example
above is silly, and maybe "epmd" isn't the best name for the protocol, but
you get the idea. I think normalizing that in the way so many other services
are normalized would be a big win, and would also allow implementations of
"compatible nodes" that weren't ad-hoc libraries.
