Hi,

what about this:

http://zeromq.org

ZeroMQ zero-em-queue, ØMQ:
 Ø  Connect your code in any language, on any platform.
 Ø  Carries messages across inproc, IPC, TCP, TIPC, multicast.
 Ø  Smart patterns like pub-sub, push-pull, and router-dealer.
 Ø  High-speed asynchronous I/O engines, in a tiny library.
 Ø  Backed by a large and active open source community.
 Ø  Supports every modern language and platform.
 Ø  Build any architecture: centralized, distributed, small, or large.
 Ø  Free software with full commercial support.

I'm not quite sure what you're suggesting. What do you want to do with it? Provide it as an interface for broker plugins or something?

I guess that it would be enough to have a library and/or set of functions to use zeromq. I second this suggestion, it would be very useful to have the chance to have programs in other languages and to be able to communicate with Zorro through zeromq!

EDIT... I haven't tested zeromq with Zorro yet, but I think there would be nothing to do, as zeromq has already a C/C++ version... It would be a matter of trying it and see if it works without further work

Oh, in that case you can grab ZeroMQ binaries and call the functions in the DLL directly: http://zorro-trader.com/manual/en/litec_api.htm

To make it easier you might want to write a wrapper in C/C++ that has does most of the interaction with ZMQ and exposes a simpler API to Zorro.
