[erlang-questions] How to get pid of remote registered process

[tsuraan]

I have a JNode with a mailbox that has a registered name.  I can send
messages to this mbox using the { name, node@REDACTED } ! msg syntax, but
I can't figure out how to get the actual pid of { name, node@REDACTED }.
It looks like what's been recommended in the past is to use
rpc:call(node@REDACTED, erlang, whereis, [ name ]), but that doesn't work
on JNodes.  Is there a different way to get the pid of a remote
process?
