Ah, okay, this is where it really distinguishes itself from a basic 
stream of sound information - but, it just points out limits in HTTP (not 
being able to fetch a random subpart of an object, only the object 
itself).  Though, munging the URL to store this subsection info in 
path-info or query-string might not be bad, and all this can happen 
*outside* the server through a smart client and a CGI script.

Either way, it doesn't look like we need to supply direct support for it.
Besides, I don't think their business model allows for public code server 
implementations anyways.  In fact I don't think it even allows for a 
*publication* of their protocol.  harumph.

God, I hope they kill "make a long-distance, even cross-country phone 
call for the price of a local call using the internet!" services before 
it's too late.

What about VRML?  :)  The big debate over on that list, of course, is 
just how orthogonal the language should be from the networking it sits on 
top of.  Oh, and behaviors.  Oh, and avatars.  Oh, and cyberspace and 
virtual real estate and and.....

It's going to be an interesting couple of months.
