Thanks Irmen. I think that could be the solution I am looking for. The main process will be native python so it can be used to host a pyro daemon even with lock. The jython will be a subprocess that takes the daemon's uri and use the pyrolite library to make the communication. The only trouble is that I will have to involve two more java libraries but I don't think it is a big of deal. Will try it and post the source code if possible.
