On Android, fields work great.  Which makes sense, given that the 
scroller is just an overlay to handle the interaction, so anything that 
can be scrolled via script should work in response to the scroller messages.

I haven't tested field scrolling on iOS, but the whole business about 
needing to make a field as tall as the textual content and then wrapping 
that in a group is, to be candid, insane, so I'm hoping iOS scrolling 
can be made as graceful as Android scrolling is now.

It's more than a little un-xTalk like to need to hand-script the 
instantiation of mobile scrollers for scrolling objects at all.

But as long as it works for scrolling groups, it should also work for 
fields. Anything that can be scrolled via script should be scrollable 
via script.
