Chris,
I do not completely follow. Last year when we were working on a large
porting project for a client of us we had to use DO, but we wanted
also to use binding. I wrote some very nasty hacks (and had to poseAs
few times), but i managed it so far that the bindings start working
reasonably well over DO. My solution was far from universal, but
based on my experience with the ObjC version of EOF (I had a
framework similar to the bindings - just 10 years earlier - around
MiscKit times if you still remember ;-) an universal implementation
should be possible.
And I do not see why performance will be of a concern if DO is used
to chat between different threads of the same task. Of course I might
be wrong, but at least I did not observe any noticeable slowdown with
our implementation. We also filed several radars on this subject...
cheers

Bindings, KVO, and KVC are incompatible with Distributed Objects.
Cocoa Bindings is not supported over D.O. to proxy objects in 10.3
and 10.4. The (void *) context parameter to the addObserver:...
method will prevent it from ever working as it is, not to mention
certain performance things that I believe Bindings/KVO/KVC does may
also get in the way.
