Yeah, you can't dump functions with upvalues.

If I understand you correctly, you want to send a data structure from
one Lua universe to another Lua universe that may be in a different
address space, right? There are lots of ways of doing this depending on
your exact data structure, but the simplest is probably to serialise the
data structure into a string and send that. (Simple, but not
particularly efficient.)

The code for this is pretty trivial; I don't have the 5.1 PiL, but the
5.0 PiL has a discussion of it here:

http://www.lua.org/pil/12.1.2.html

This version produces Lua code, so the unserialisation procedure
involves simply executing the string.
