data encryption + Biometric security

There are many competing technologies behind fingerprint scanning and
evaluation techniques, some which are rather weak and others which are
quite strong. Forming opinions based on tests against a small subset of
them is not exactly doing due dilligence.
Watching things like tv's MythBusters defeat fingerprint sensors is
interesting and entertaining, but when you know they're using several
year old, out-dated technology for the sensors they evaluate, you might
suspect that there's more to the story that they're telling you.

First it sounds a very smart idea to have biometric security, but sorry,
when I give you some sceptical feedback.

Biometric "security" wasn't discussed by the OpenMoko community yet, I'm

A file could have an encrypted filesystem, acess is given only for a
while and only while GPRS connection is on.
If it is lost, use Internet or an asterisk server to unmount this file.

Sounds nice, but I have doubts that a fingerscanner is given real
I will going to play with my (Debian) Crytoflex card, but not to make
access more easy - to make it more secure.
So when I have to lost both - my Neo and my Cryptotoken.
projectblackdog.com costs 199US$+Chiping for me to expensive.
But this is just my 2cents....
When somebody has such a finger scanner and likes to make it running
with OpenMoko would be fine - but expect also some feedback that the
fingerscanner concept is not so secure as it looks like:
