I've just discovered pyjamas today. This morning I thought it sounded like an awesome way to develop cross-platform applications. But now its early evening and I still don't have pyjd working on Ubuntu. I've become very discouraged with OSX, and I probably won't bother with Windows unless I can get the first two.
Even if I do get it going, how would distribution work? Am I going to be able to use freeze.py to make bundles? Clearly if there isn't even an Ubuntu package to install pyjd (or xulrunner or python-webkit that works right), I'm not going to be able to release a package that depends on pyjd. It would be encouraging to hear if there's any project or product that is doing this successfully (Preferably open source, but anything would be interesting.) I noticed there's several web apps using pyjs, but haven't been able to find anyone using pyjd.
