How do I make the private key on a OpenPGP smartcard non exportable ?

I quite disagree, here.
A smartcard could be useful anyway, at least as a "portable keyring" (if
it didn't need initialization on every machine...).
And key export could be controlled (like in MyPGPid card): private keys
can only leave the card encrypted under "certified" keys.

BTW, for the really "paranoid", readers with an integrated pinpad are
available: the PC never sees the PIN, so no installed sw can spoof it.
(even if what I'd prefer is a card w/ both a pinpad and a display...).
