Well, according to the JBIG2 page,
http://www.jpeg.org/jbig/faq.phtml?action=show_answer&question_id=q3f042
a7298c94 that may not be a problem.  Then again, it may have an issue
similar to LZW.  I hate to introduce patent issues (and free software
issues) here, but it might be perfectly valid to introduce JBIG2 into
libtiff without licensing issues.  They also make reference to free
licenses for the codec.  I don't know if that means the developers will
get free licenses, and the users will have to pay, or exactly what the
terms are.  That will probably require work by someone to contact IBM
and the other patent holder, but it may very well be possible.  I would
be willing to chase this down if there is an interest.  Hey, you never
know until you try...

A problem with JPEG2000 and JBIG is that they are covered by patents. 
The existing compression schemes supported by libtiff are now believed
to be patent free.
