The bindings issue is a problem here - it's probably difficult to 
implement a spec based on the PropertyChanged signal if bindings don't 
support it.  However, in general I think we should make this spec as 
"right" as possible.

We want v3 to be a long way off, and to involve as little change from v2 
as possible (so we should be getting the really disruptive changes in 
_now_).  Interoperability specs that keep changing are kind of pointless 
- in order to actually interoperate, media players and clients will have 
to implement multiple versions.  We have very good reasons to move on 
from v1, but I don't think we should work with the assumption that 
there'll be a v3 soon.
