I have much food for thought. :-) Actually, my plan is as follows: At each peer, I postulate a single persistant data store holding a rather complex set of data (primarily file attributes and routing information, etc.) I also have a client process to talk to each peer and to its own file store, exchanging data with other file stores. I have the portable spec for the communication messages, but I was hoping to defer having to deal with that for a while, in favor of ensuring that the algorithms will work as I think they will. If I can make the peer-to-peer stuff look like message passing or calls to protected objects, then I can layer the procedures that do the formatting into XML/MIME/BEEP/etc on top once I know it's worthwhile. Of course, this means I also get to release it earlier, with the understanding it only interoperates with certain versions of itself to start. > You're > going to have to do a lot of work to guarantee representation of every > record type you want to send/receive. Yeah. In reality, I've already defined the format in MIME and XML. I was just hoping I wouldn't need to implement the translation from Ada message sends into text libraries and such until after the rest of the system started humming. -- Darren New / Senior MTS & Free Radical / Invisible Worlds Inc.
