Subject: WebSocket based prototype
Message-ID: <CAFvQSYTGQkAy2rbE8vVDGxt1ku87Dmj4xWUwd42n=vBtC-K9VA@mail.gmail.com>

Hi again,

Out of curiosity I hacked together a websocket based prototype the last few
days - its really only a prototype.
Its amazing what WebSockets do in high-latency environments - SwingSet2 was
almost unuseable over my UMTS connection (~130ms ping),
while now even moving windows feels almost smooth.

Downside is, there is almost no browser support, and (suprise, surprise)
binary data transfer doesn't work (yet).

It also shows the hard work put into damage-tracking, and
scrolling-optimizations actually work, if there wasn't that horrible latency
burden of HTTP.

In the case you are curious:

(only tested with Chrome14)
