Hi Tim,

	well regardeless of it's unpredictable nature, money, as medium of
exchange measure unit it still *is* a unit. So I don't see why to evade
that. 

	But I concur with you about complexities in the relationships and
(worse yet) it's historic values. Concretely I don't need (by now)
historical or multicurrency features so I'm ecouraged to use it as unit. But
if for any reason I do, I think I will have to do something regardeless
money it's a simple value or a unit. I think I'll still prefer money as a
unit.

	cheers,

Sebastian
