I created the Generic Erlang Port Driver to have an easy way to 
automatically generate a port driver or port for C or C++.  The code 
generation does not rely on an idl file but instead uses 
boost::preprocess to use macros.  The code is still in development, but 
should provide another way of creating port drivers automatically.  The 
port drivers are generated only with usage of outputv, for efficiency.  
The message structure is determined from basic types passed with the 
native byte order.  A facade pattern could easily be added as an 
interface to the port driver.  You can find the code here:
