@ArnoldKrimins - no, they are just DialogViewController descendants, which is specific to the (client) application. Basically just a UITableViewController.

@Shogan: I think this might be old, dead code. You used to have to keep track of things a bit more aggressively in MonoTouch than you do now, to avoid being GC'ed. I doubt there is any need for it.
