In Twisted, lots of classes exist to help you do this. For simple length prefixing, have a look at any of the *stringReceiver classes in twisted.protocols.basic. (NetstringReceiver, Int32StringReceiver, etc) You can transmit binary data over many higher-level protocols as well; HTTP can handle binary entity-bodies just fine, as can twisted's "native" protocools, PB and AMP. _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
