I believe we already have a U2F prototype for Linux. In general we are quite selective about which applications we take on development and maintenance responsibilities for. Given that this is the most open source hardware USB authenticator we hope the communities that value this level of openness, design assurance and design verifiability will adopt the TKey and build whatever applications they need for it. Having said that we see lots of opportunities for us to make it easier for developers to build what they need.
