How does the procmail recipe know if the person is a subscriber of one list
or another?
I want people on A to not be allowed to send a single message to both A
and B. I someone sends to both A and B it should hit procmail and
automagically be send only to B.

If the addresses are aliased through the SAME local delivery alias, then
only one physical copy of the message should actually be delivered locally.
Personally, I'd be kosher with just bouncing back the message whenever it
is crossposted, regardless of who is crossposting it. Correct the problem
at it's source, rather than fixing it up behind the scenes.
[If someone on B sends to A and B, that would automatically block the
message to A.]
"lists" sure is a descriptive term of what you're using for a mailing list
processor. If it is Smartlist, there's a specific list for Smartlist
questions. If if is something else, please define what it is, and how you
have procmail hooked into it in the first place.
