The problem is i want to have total control of the overhead, while being able to optimize any code i want. If i can place all of the heavy overhead in a non-critical thread, it's just fine. As someone said previously, there is a way to write major code issues in c++ and glue them together with python. This is not far from what i have foreseen. I though of a thread running digital processing over some stream, and some other just for management issues, possibly receiving orders from a script. The first should be c/c++, while the second could be anything else. Strange as it is, you saying i have to do it from scratch is REALLY good news to me. As it happens i have this end of graduation project, which was more or less targeted to the requirements i asked about in my first mail ( althought it was not my main proposal ). As it goes, i can say to my professor i really couldn't find anything very close to the project i have going on ( it's almost done by now ). The bad news is i have to use my own code, which was written mainly in a rush, and lacks a little discipline in some points. If someone would like to take a glance, i would be glad, though it lacks documentation, and is commented mainly in portuguese. By your news, i have second thoughs of continuing it to serious work, maybe in a master thesis. Again, thank you all, Fabio
