Just got internet service back, so I'm back online...

I suppose that is usually the case.  I was thinking of typical web apps where 
the majority of the data in the response is generated HTML, and the data 
loaded from the store may merely consist of some small amount of raw data.  
It's not unusual to load a few K of data and use that to generate a 50K web 
page.  But that may not the the case, in general.  Ideally we would support 
either mode of operation, but we should probably just pick one for now.

Hmm.  Good point.  So how is it that a client, who only knows to connect to a 
VRS through a particular publicly known IP address, will be connected to a 
different LDS?
