It's a persuasive argument.  I'm already dreading the integration
problem when you try to federate the member databases of those 1000
lists.  Adding another list of addresses that need to be collated
could be another headache.  OTOH, since the whitelist is /only/ a list
of addresses, a simple union would probably suffice (you don't have
the same problem with unioning member database since non-members don't
have option flags and other data).

So when are you going to start collating the whitelists from all the
TMDA sites and sell the opt-inside-out lists?  :)
