Nice initial attempt. Besides the encryption issues mentioned here, here's my suggestion. This needs to be built into a mobile twitter application (non-jailbreak), I use pgp encryption/decryption programs on my iPhone and they are fast. Also, you should allow the use of any key server that the user wants, as known public key server access can be blocked by a country.
