Well, now I'm wondering if it should be named ar_lookup, ext_lookup or
external_lookup might be better, it's not ActiveRecord limited. Your
choice.

The thing is it will grab the ${f:xx} values when the 'set' is
executed, maybe you need something that reads the values when the
ext_lookup() is executed...

Your knowledge of Rails forms is vastly superior to mine, I'd be glad
to help, but you have to show the way :)
Maybe the find / lookup logic can be used once again, at update time,
to locate the ActiveRecord.
