Securing multiple keys with one smart card

I did, but I understand that is not supported by GnuPG
(currently). I was hoping that I was mistaken about that limitation
or that there was a work-around of some sort.

My goal is have my private key material protected by more than just
a usable (that is, a long but not very long) password. Ideally with
a card as a second factor.

It is my understanding that GnuPG only supports OpenPGP Card smart
cards. Is there another card type that would work?
My card has space for plenty of keys so storing all the keys on-card
is feasible and would work very well for me. 

> An updated specification of the OpenPGP card will support more keys.
I saw some discussion in a dev. mailing list about supporting more
than 3 keys, but got the impression it was not likely to happen. Do
you have more information or can you point me to where I can learn
more?


With gratitude,
