thank you for mentioning these, chris. the information on pyjd is slightly out-of-date. * pyjamas-desktop was merged into pyjamas as of the 0.6 release. * there are now three alternative back-ends for pyjamas-desktop, (just as there are three major web browser engines). MSHTML, xulrunner and webkit. Opera's engine cannot be included because Opera's developers have not responded to invitations to provide an engine / library to which python bindings can be added. when they have provided python bindings, a port of pyjd to use them can be done in approximately two weeks. * the webkit-based back-end is the least-recommended, due to intransigence of the webkit developer, mark rowe. mark rowe has shown consistent disrespect for free software contributions to make webkit with glib/ gobject bindings actually useful and useable, and has ensured that anyone who wishes to proceed with getting webkit its glib/gobject bindings will have an unacceptably hard time. efforts to work with the other webkit developers, which were proving successful, were deliberately destroyed by, and terminated by, mark rowe. * the MSHTML-based back-end is surprisingly the most successful of the three pyjd ports. it requires _very_ little in the way of libraries to be installed: only python-comtypes (at 250k) which is in complete contrast to the other ports, which require whopping 30mbyte installs of libraries and dependencies. * the xulrunner-based back-end is the best option for unix-based systems. the design of xulrunner's core infrastructure, XPCOM, however, is slightly ... "incomplete". it is based on DCOM, but does not provide the exact same capabilities as DCOM (no coclasses). the upshot is that current releases of xulrunner work perfectly well for _everything_ but 2D SVG Canvas "Image" loading. (i have a patch for xulrunner which fixes this one single error) so - it's a mixed and interesting bag of tricks. full and comprehensive non-javascript bindings to web technology seems to be a thoroughly misunderstood and underexploited area, with several variations on the same theme being available from several competitive sources. the nice thing about pyjamas is that just as pyjs makes all the differences "go away" when pyjamas apps are compiled to run in web browsers, pyjamas-desktop makes those differences "go away" when pyjamas apps are run as pure python on the desktop. l. -- http://mail.python.org/mailman/listinfo/python-list
