B2???  No, you must be kidding.  You *don't want* B2.  (It may be required
for something you're doing, in which case you may *need* it...but even then
you won't *want* it.:-)

B2 is a higher level of security than C2.  I'll leave it to the orange-book
mavens to explain the differences; suffice it to say that if you think the
flaming you've seen in this newsgroup about C2 is hot, you ain't seen
nothin' yet.

And no, B2 is not required for V.4.  It's an option--I think MLS will take
you to the B2 level.
