Maybe the best way is to put a 'thumb' data source into Customers
instead of native one. This thumb should translate all messages to
SkyDivers' data source. I'm just considering on specialized racks which
implement non-standard api, such as 'findItem( criteria)',
'itemValues()' or something similar.
By the way, racks should have a kind of 'scanning' api, like Zope's
Folders, at least they should have itemIds() method.
