I think Keyhotee should run for 6 months to a year smoothly first before getting into mobile devices. Grow a user base and work out all the kinks first.Having a mobile version would help with gaining a user base, since people are using mobile devices for more and more
i guess 1# priority is start of keyhotee. Then alpha/beta tests and when it works stable next step all other os, mobile etc.
For imagination i guess it will work like facebook login when it goes mainstream .. when you have transfered your ID private key from computer before
bytemaster pls correct me if i'am wrong
