It was the first "Open Source" Conference in Hong Kong.  Audience was about 40, but there are only three GnuPG users, and two are already my friends. :-)
Anyway, I think that I did my best to explain Free Software Tool, Free Software Firmware, and Free Design of Hardware.  All are equally important, and I say that I'm proud of my achievement of the product.

On the other hand, discussion at Dim Sum Labs on Friday was great.  It was really great hackerspace.

At Dim Sum Labs, people discussed on possible hardware backdoor inside Gnuk Token.  Well, I rely on Seeed Technology's manufacturing process entirely, and I let them get parts, including the MCU.  Thus, I said that if you care, I'd recommend getting STM8S Discovery Kit, instead.  It's expected usage is for STM8S development.  (Ab)using its part of STM32F103 would be best to avoid hardware back door threat.  It's less than USD10 and its intended purpose is education/promotion of another MCU, it is unlikely we have hidden feature with its STM32F103.
And someone noticed that STMicroelectronics is not US company.  Another person discuss that it would be safer if MCU were implemented by FPGA, then its functionality would be under user's control.  My answer was that it would be easier for an attacker to attack FPGA with full of features, than attacking a simpler MCU with limited capability.

Thanks Yutaka!
