Bindows
Bindows is a cool hack, but really, what’s the point?
The site claims that “Bindows applications can be as rich as any modern desktop application” but when you choose to write a desktop application instead of a browser based one, the reasons are usually ones that Bindows doesn’t address.
Things like tray icons, drag/drop, or even something as simple as access to the local file system.
But hey, it’s AJAX.
