...and from the theory side of the house...

My gut is also to return boolean and provide an async mechanism for
determining the cause of the failure.  We are dealing with an object,
which has some degree of persistence, so it should be possible to retain the
last error code, no?  Instead of using a handler, you would follow a failed
request with a call to the object requesting the error value.  The only
problem I see with this is that it could get very messed up in a
multi-threaded environment (which is why a handler would be useful).

I like the idea of sticking as close as possible to existing interfaces.

Again, my perspective is one of theory and I rely on Mike to deal with the
practical aspects.
