I tested it on windows 7 with python 2.7 and pyjamas 0.8 download from git 4 days back. Since i tested all of them with pyjd the browser will be mshtml i guess. and i found these issues. (I don't know if they were fixed/found earlier)
jsonrpc the readme says that in order to run the python CGI server go to examples/jsonrpc/output and run python PythonCGIServer.py but the file PythonCGIServer.py is located in public instead of optput (infact their is no output folder) after starting the server i ran pyjd JSONRPCExample.py i got a window in which it showed the 404 server not found page and under that i can see the JSON-RPC Example. When i try to send some test text to python CGI server i get http error: 12029: addonsgallery when i clicked canvas2d i got some errors at the prompt and when i clicked canvas the window got closed and at the prompt i get an error TypeError: expected a character buffer object > >> You got the point >> that i wanted to make, that the transparency effect which is achieved in >> google gadgets ( I will try with the solutions that you gave and do a >> more indepth research on it). > yeah it basically means depending on the window manager for various things. > > which reminds me: would you like to help create a python-based window > manager that uses pyjamas desktop as the actual "window manager"? > that way, it would actually be possible to just have transparent > widgets... as pyjd applications or javascript! > > i started this project 2 or so years ago - > http://sf.net/projects/pyjdwm - it involves using a very very very > basic NPAPI plugin which tells pyjd what its X-windows ID is. > applications can be fired up into that X-window. the key here is to > "re-parent" the application, but you can ONLY do that when running as > the root window... hence the requirement to do this as an actual > window manager. this looks interesting. Since i am still trying to understand how the whole thing works. I am a bit confused on few things that i will list in my next mail.

I went through this link http://www.gnu.org/software/pythonwebkit/ which i guess says about python bindings for webkit. But i don't know if this document describes about do's and don'ts or shows the various ways in which one can achieve the required result. One more thing why can't we create a blank canvas and make it a bit translucent and this canvas is a browser with out borders. It is a wild guess. I don't know if it is possible and i guess thats what you were point to when you referred to pyjdwm.
