I suspect find person by state would return quite a few persons! So
returning an enumeration of these to the client by any means is
probably not a good idea. Probably better to have a protocol
that will return a collection of serializable copies of just the bits
you need to populate your GUI widgets (plus some PK's so you
can get back the selected lucky person).
