How about:
legacy app call XML-RPC service "gnumed archiver"  with parameter patient ID
- the XML-RPC server gets the call
- spawns an instance of the archiver module
- returns a handle
legacy app is happy, instance can close:
- XML-RPC call to server "close handle <n>"
- server closes instance with handle <n>

If legacy app wants gnumed module to do someting, it just accesses the 
module's API via the same XML-RPC server, passing handle, command and 
parameters as parameters.

On the client side, you can have a simple XML-RPC client that can be piped 
into via stdin/stdout or whatever.
