Voice Mail to Electronic Mail
Would allow you to forward your telephone to a server that would record the callers message and deliver it to you as a .wav attachment to an email message. Possible technologies for this are Asterisk and Oracle Collaboration Suite. With an adequate server messages could also be stored for retrieval via a phone interface.
VM Rover looks like an interesting client specifically designed for voice mail.
ShuttleTrack Voice Response
Would allow you to get a voice announcement of the current location of the shuttles. An instant message alternative could also be provided.
