well, the current implementation of the YP server does not prevent such 
things from being implemented....although, honestly, the reason the YP 
server was designed as such was because I didn't feel it needed that type 
of detail...I think the existing YP approach was just fine for what it 
needed to do, building a next-generation YP was something that Jack Moffitt 
wanted to do, and had gone quite a bit on the design, although when all was 
said and done, there was noone really to implement it...or noone would, or 
noone had time, you pick the reason...Have a working YP I thought was 
pretty critical to icecast2 (especially since the icecast1.x one kinda bit 
the dust) and rather than reinventing the wheel, I thought it best to 
simply pump up the tire....

XML is not really suited for this type of request, you don't need 
structured data for YP communication, you just want a varying number of 
parameters, which is currently possible given the current implementation.

another thing about the design...The YP server needs to be fast, efficient 
and scalable...XML is extensible, but not terribly fast and  efficient...

just because you can do something doesn't necessarily mean you 
should.  Adding additional attributes to the listing is pretty much a 
trivial task, but simplicity rules when displaying and searching YP servers...

well, that is what I think anyways....

thanks for the input though...you ideas are good.
