I have created a T1.1 (beta) branch of PyDECnet, which seems to be working well enough to take for a trial run. I currently have it running as the HECnet mapper node (28NH). That's not a major stress test since it's an end node. Assuming things go well I'll switch PYTHON, the area 41 backbone router, to this version in a couple of days. If anyone wants to try this, you can find the code at svn://akdesign.dyndns.org/pydecnet/branches/t1.1/pydecnet -- in other words, same Subversion server but at the branches/T1.1 subtree rather than trunk. Be sure to read CHANGES.txt, there are some small changes to the config files. And if you use the API (HTTP GET or POST to /api, in V1.0) you'll need to make changes; I dropped that approach since it wasn't workable going forward. The replacement is actually much easier and there are some support modules ("connectors") to simplify things further. See doc/api.txt for details. paul
