The new hipness is comet (new for me, @ least), & this plugin will  
take care of the inconsistencies between browser capability for  
streaming.

- For IE, it uses the ihtmldocument2/iframe hack, as used with gtalk  
& described in http://alex.dojotoolkit.org/?p=538
- Mozilla & Opera use xmlhttprequest, with slightly different  
implementations.
- Safari & Konqueror (webkit) currently is not supported, due to lack  
of support for xmlhttpreqest's interactive readystate.  I have not  
tried to adjust the iframe technique for this browser engine yet, so  
I don't know if it's possible.

Comet still requires a server-side component for efficient  
processing, but @ the simplest level, all that's needed is a while  
loop with a sleep call (example uses this technique).

I don't consider this a full release yet, as there are several  
modifications I plan to make, but feel free to comment & offer  
suggestions about how to make it more efficient.
