the benefit to the pyjs approach is 100% client side operation, so it can run without online access.  additionally, the python-DOM version (or the pyjs version if proxying thru a local daemon) could potentially direct install from the website, leading to "install now" functionality.  lastly, python means you could use the same lang to write the front end and the backend, and communicate using JSON messages.

as a professional web applications developer by day, i can vouch that writing webapps requires knowledge of about 4 different haphazardly implemented "standards", requiring far to much painfully acquired knowledge.  by using a library like pyjamas, you allow anyone with python experience to write incredibly functional plugins/modules, and share maintenance load.  django is a great platform, but after i discovered pyjamas about 1yr ago, i haven't looked back, and am convinced that compiler technology is the only sane way to develop complex and maintainable web-based applications.

Out of curiosity why is everyone so again just writing Javascript? Everyone seems to want to write in some other language and then compile to Javascript these days. --Kaiting.

well for me at least, it not 100% related to javascript itself; JS is an incredibly powerful language that will let you hang yourself again and again :-) primarily, it's: ) JS is completely unstructured. powerful, but causes developers to implement many things that would be a part of the core syntax in other langs ) the ^^^^ causes many different impls of the same, and new devs to misuse the really great things about JS, like first-class closures. leads to absolutely obtuse and horrendous looking libraries, with weird semantics for its usage, like passing objects to emulate named arguments, and a hundred other more prudent examples. ) umpteen number of naunces between browsers, browser versions, and half-eaten standards. maddening. combined with [some] similar problems with both HTML and CSS, and it's enough to drive one ape-sh*t. soooo.... i use a python abstraction to give me my favorite language and all it's goodies while also shielding me from platform variation, along with widget libraries to support the build-once-deploy-everywhere thinking. yes, JS has some decent libraries, and widget sets (don't say extjs). but pyjamas can be ran as a 100% python desktop app too. so ultimately, compiler tech gives me a 100% cross-desktop cross-platform cross-browser cross-version solution... try it out, it's like finding a nude beach after walking 100km thru a blizzard :-) C Anthony
