For that I would use any of many available communication protocols. Putting distributed annex on top of it is relatively straightforward. BTW, if you know how to tell GNAT to use a custom transport layer, let me know. I have an implementation of distributed annex for parties running as processes on the same host. However, I would not use distributed annex for a mesh of independent nodes. It would face same problems as CORBA: rigid, fragile, unmaintainable and critically slow (RPC). I would use some middleware deploying publisher/subscriber mechanism instead. There are lots of, alas, most of them are commercial. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
