GTK Selector has interface to build different Card Store providers. We 
already have File System and Card Sync Card Store providers. Looks 
like for your case, you need a memory based Card Store provider that 
loads cards from USB key when there is DBT_DEVICEARRIVAL notification 
and remove the cards from memory when Selector exits or 
DBT_DEVICEREMOVECOMPLETE event happens.

I think this might be very close to the SmartCard support that FC2/
Gemalto people are implementing. The change might be only in the type 
of device detected and how to auto-import the cards from usb key from 
a specific location. May be we should ask FC2 folks on their plan to 
contribute their code to higgins and try to build something on top of 
that for usb key.
