I believe that ability to use Gemini PDA as USB keyboard would be extremely proficient for those of us who have to setup/debug
normally unattended machines, use standalone tablets but have to enter BIOS occasionally and/or needs & wants compact external keyboard with them at all times for any other reason. Implementation of this feature would require a modified kernel with enabled USB keyboard device profile. If poll shows most people here want this feature, I'm going to petition Planet Computers asking to include this USB connectivity option in their mainline kernel, so that it is possible to use by just installing an app and selecting keyboard USB profile when connecting to other device.
