I hope that at some point in the future we can also unbundle user 
accounts and assets from that as I think those really belong to the user 
and can be anywhere on the net. A user would then merely delegate 
authorization to access those services to a grid.
I really would like to have things as decoupled as possible which of 
course is right now a bit problematic when things are based on the 
Linden viewer.
But you could always group them back into one thing again later.

Hm, why is that? The client could get some token and use that (e.g. via 
the OAuth signature mechanism) to access those services (inside or 
outside the grid).
