Picture signatures as (hand-held device) biometric passwords?

An interesting variant on biometrics, can't easily be
reproduced with
pieces of one's body separated from the whole, and involves
in part
something remembered. No hard numbers were provided on FP/FN
rates.  Also,
no mention of how "compexity rules" might be
handled. CISOs might not
be too happy without a warm fuzzy that their users have
decent passwords
on their BlackBerry devices. Is my "X" more secure
than your "X"?

This may not work for everyone, some people are more
verbal-sequential
than visual-spatial. I for one don't really have a stable
hand-written
signature, but have no problem memorizing long passwords
(and can store
them in a password-safe).
