Maybe the Tomu discussed in another comment here would be a good starting point. We're really focused on the Kickstarter now, so unlikely we'll have time to do it ourselves in the next, say, month or two. But the code is open now :)

I personally use a Nano, but only for limited use cases like VPN. I don't like it for web access to Google/Facebook/Github simply because it feels like someone else could get access to it easily. Of course it's more like a feeling than a real threat.

It'd be interesting to see some numbers on sales, to see if it's worth from a business perspective.

Edit: grammar
