BTW... I tried this out, it seems to work fine.

It still feels "wrong" to intentionally leave an HTTP connection open  
like this, but it seems to work okay when I test it.

I'm building some new javascript for the jowles interface that uses  
async requests, along with an XML service interface and will publish  
the code to the hbmobile project ( 
hbmobile/ ) "any day now." I'm starting to document this stuff at the  
Jowles wiki page.

Tim... thanks for the idea of using async requests, it should have  
been obvious, but it wasn't, so thanks for pointing it out.
