How hard would it be? A couple of ideas for future Google services

Just a couple of ideas I had for future Google services. I can't imagine these would take long to implement.

• Dictation and transcription service. Leverage Google Voice's voicemail transcriptions for longer messages, either phoned in or submitted in audio files. Compete with CastingWords. For an additional fee, add light human editing.
• Voice appointments. Allow people to speak their appointments into Google Calendar, using the same syntax as Quick Add.
• Video voicemail. Integrate Google Voice with Google Video/YouTube capabilities to allow Seesmic-like messaging. This might take off more easily when Android phones have forward-facing cameras, but it's device-independent.

Have any other ideas that involve leveraging current Google (or other) services? Leave them in the comments.
