I would like to provide a client a Choice control on a form that has values that resolve to type People.  This should be limited to the 10 or so folks on their team.  I am hoping for a true dropdown, not just a people picker restricted to the people I maintain in a SP Group.  Additionally, the value, once selected, writes back to the column in the list as a true person field so that I can use it for task assignments, view filtering based upon oMe], etc.

As a last resort, I could use a Single Line of Text for their dropdown, and then use a Lookup to a secondary list to write back the person to the field, but am hoping for a more elegant solution.

Thanks in advance!
