USB Token for GnuPG

I'm new to this list, pardon my ignorance if any.
I have an idea for USB Token which speaks OpenPGP card protocol, and
its Free Software implementation. The use-case will be like FSFE
membership card, but it won't require USB card reader.
I have done a little development with Atmel AVR ATmega328P 20MHz.
Currently, my mockup code works for "gpg --card-status" and
"gpg --clearsign". RSA signing takes five seconds or so. Not that
good, but not that bad, I think.
I know that it's totally not secure than Smart Card. Still, I think
that it could be used for some cases which don't require much
security, and it could be a reference device side Free Software
Does it make sense?
Attached is a picture of my device. Any comments will be appreciated.
