Are you referring to the problems Gary ran into when he modified the
form setup machinery? I ran into the same problems in our application,
which led to the mods to make LocationProxy work with security proxied
objects.

Apart from the "works/doesn't work" issue (your previous point), are you
concerned that we'll see LocationProxy popping up whenever we need
location-sensitive lookups? Would that be a bad thing?

I've found LocationProxy to be essential providing location-specific
lookup capability in more than forms. E.g. I often location-proxy
objects in events where handlers perform operations that want local
authentication facilities.
