I finally decided to take a wack at a bbdb to org-contacts converter.
I'm attaching the file below.  It should prompt for a file and
insert all your existing bbdb records into the file using the formats
and fields that I decided was appropriate ;-)

(require 'bbdb-to-org-contacts)
M-x bbdb-to-org-contacts 

Now...  I've been using bbdb for a very very long time.  That means that
I have a lot of records.  That means that this was a good chance to find
out how well org-contacts scales.  The sad news is that it doesn't.
Once I point org-contacts at my newly generated file containing 831
records it make org-contacts really really slow down.  I wouldn't care
about the normal record searching process for just looking something up,
but it makes loading a message in gnus unusable (5 second delay per message).

So...  I need to filter down to "current ones I need to keep" or we need
to optimize the contacts a bit to cache file points where a record for a
given email address is stored or something.
