Oh, this is cool! It was written for my presentation at LUG Radio Live this past weekend in
Wolverhampton (UK). Gives an idea of the compactness of code you can get if you allow concurrency to be naturally handled in the system by thinking of them as communicating components.
It's a powerful analogy, for sure! Right inline with the Smalltalk way of thinking about programming, something I truly appreciate. Come to think of it, the combination of Vista Smalltalk/DLR[1] + IronPython + Kamaelia + Silverlight (once Silverlight gains support for sockets) == my mouth drooling with the combination of possibilities. :D Peter (Cc'd): Have you had a chance to look @ Kamaelia[2]? [1]: http://vistascript.net/ [2]: http://kamaelia.org/ The first file (220 lines) is a generic peer. The second file (170 lines) is
a source peer - specifically it captures BBC Radio 1 off broadcast from DVB digital TV broadcasts and then restransmits it. (Its an example source - someone actually intent on using this would have to replace that source with a source they have a license to redistribute)
Am playing with this now. In the mean time, one problem I ran into that requires the yet to be implemented nested yield statements in IP 2.0, IronPython 1.1 (1.1) on .NET 2.0.50727.42

Beyond the above issue, things seem to be playing nicely which is really great! I'll run through the provided sample now and let you know if I run into any issues. Thanks, Michael! -- /M:D M. David Peterson http://mdavid.name | http://www.oreillynet.com/pub/au/2354 | http://dev.aol.com/blog/3155
