[erlang-questions] spawning funs on other nodes that does not contain my module

[Lukas Larsson]

It is not possible directly, you would have to get the code to the other
side somehow. code:load_binary is made specifically for this purpose,

http://erlang.org/doc/man/code.html#load_binary-3

Just use rpc:call(MyNode,
code,load_binary,[mymod,"mymod.erl",BinaryModuleCode]) and off you go!
