[PEAK] PeakPlace, Junction

[John Landahl]

PEAKers, there's now a collective project space called PeakPlace at 
tigris.org:

   http://peakplace.tigris.org/

There's a CVS repository there for collaborative work on PEAK-related 
projects.  The focus is meant to be for actual working projects, though 
larger PEAK examples are also welcome.  Let me know if you'd like CVS 
access.

I've checked in the code for what I'm calling "Junction".  It's the 
initial version of what will be a message-oriented-middleware utility 
built with PEAK and Twisted's Perspective Broker.  It has a long way to 
go, but it can already take some of the pain out of using Perspective 
Broker and also includes a basic publish/subscribe mechanism.  
Unfortunately there's no documentation yet (other than what's in the 
interfaces), but there is a simple working example.

Coming soon: a shift to real messaging (e.g. full decoupling of method 
calls from objects; messages used for pub/sub), SLP (rfc2608) 
advertisement and discovery of messaging services, and some quality of 
service guarantees (e.g. messages saved locally if unable to send, saved 
on messaging server if unable to deliver), and communication alternatives 
beyond PB (e.g. CORBA, PyRO, SOAP, XML-RPC, and there's no reason why IRC 
or Jabber couldn't be used for pub/sub; even SMTP should be a possibile 
transport).

All comments and critiques are welcome.
