Proxies! pdlua has an implementation that seems to work for me, there
might be a better way to implement it for a C-based external though.

Yeah, it's not ideal, but this proxy solution isn't so tedious if you
make it generic enough, which isn't too hard.
Maybe there should be a libpdutils for such common tasks, pending
inclusion into pd?
