Data Transfer Demo
Today I found another site with a pageloading script similar to NW's, but they break it out and call it an "http buffer", or something. Anyway, basic principle is the same as with NW, you load content into a specified element via a hidden iframe, etc... yada yada...
Still haven't seen anyone else doing something like the generic parser though...perhaps I'm just out in left field with that one =)
Speaking of the generic parser and the loading queue, I built a little demo of netWindows data transport. Maybe it'll be entertaining for someone.
