"Some." For example, an image acquisition plugins needs to cooperate
with an image manipulation plugin. (The central conceit is that the
app is just a flexible shell, and all the action takes place in the
plugins: we can distribute radically different apps 'simply' by
changing the plugin mix.)

While I think comm costs are big minus for the AppDomain idea, there
may be a more fundamental problem: this is a GUI app, and the app
provides various containers for plugin supplied UserControl-s. Does
setting a UserControl proxy's Parent property actually parent the
UserControl in another AppDomain? (Yes, I know, I could just do some
experiments, but I don't really want to take the time, given that
we're not currently looking at going down this road.)
