That's what I was doing with MyPGPid: a 144k Javacard can host the
applet and many keys.
The "trick" is that it accepts the standard OpenPGPCard commands, plus
some extended commands to handle extra keys (like selecting current
enc/dec key, or safely export keys only towards user-certified devices).
This way you only need the standard GnuPG plus an helper program (can be
a simple script using opensc) if/when you need the extra functions.
