An Ardunio nano v3 might be a good choice if you want to actually make a
full KB with caps lock reporting etc. Apparently V-USB can handle 12 MHz,
12.8 MHz, 15 MHz, 16 MHz, 16.5 MHz, 18 MHz and 20 MHz [1], but the clocks
need to be precise. If you want to roll your sleeves up you could use a
larger i/o attiny such as an 18pin Atiny88/861 [2] + your own SMD board
design. You can always borrow a Nano and have a play with. Also I
am ordering some Atiny88's for the PsionKB-to-Kindle3G interface, so can
get you some also if you were interested.

Cheers,
Ed
