I did some development with Yubikey's a while back and they sent me a handful. I have two left I'd like to sell for 2BTC each/shipped to anywhere in the US.
I'm willing to ship to non-US for an additional .5 BTC.
One is just a standard Yubikey (

< SOLDThe other is a VIP Yubikey* (

< SOLD*The VIP does not come standard with the Yubikey OTP preloaded instead it comes with the Symantec OATH, however it does have a second memory bank so you can very easily load a standard yubikey OTP configuration to that second bank.
I know I'm new and with this being my first transaction and all I'm willing to send these before receiving payment to well established members, also my eBay feedback is in my signature as well.
