OCB is a nice mode, I've always wanted to use it, but:

without the ability to use it without encumbrance I'll stick with CBC+HMAC or
GCM.  I know you can use OCB under the GPL but that's too much of a hassle to
try and sort out for each user, it'd have to be completely unencumbered to
make it useful.

(I'm not saying this out of some rabid anti-patent position but purely an 
anti-headache position, since there are unencumbered, if less efficient, 
alternatives available I'll go with those and avoid the hassle).
