This is absolutely uncorrect.
I do NOT need mozilla crypto api, i do not need the entire pkcs#11
layer since my driver rawly communicates via the T=1 protocol with the
card (thanks to Sun's Java low level APIs).
I just need Java and the card reader drivers (but NOT the pkcs11),
that's the big point of the driver.

Internet explorer does not use the standard PKCS11 layer... it uses a
more sofisticated layer (CSP).
There is an open source project (actually I miss the name) that claims
to act as a wrapper between Microsoft CSP and the PKCS11 layer, but i
never tested it.

Anyone chooses his paranoid level.
There are people that do not allow Internet on their computers :)
But we're in the 2008 and the i suppose the probability to find a Java
installation in a PC is realistically high (and absolutely higher than
the probability to find a pkcs11 layer + gpg agent + pkcs11 correctly
installed )
