Writing a linked in driver is one solution to the language binding
problem.  There is the ei/erl_interface library solution for 
building C nodes and jinterface for java nodes.  You can use a
simple port interface or you can roll your own IP based message
channel.  There has been plenty, plenty work done and made available
for interfacing Erlang with the outside world.

Language bindings are by necessity not perfectly tight integrations.
Look at any other language binding, they all use a communications 
channel.  You can use Corba for instance to make it look like a 
procedure call but in the end the two domains have to communicate 
using a channel.  

So yes, it is a pain because it's not pure Erlang anymore.  That's
not much of a criticism of Erlang.
