Lots of fun ideas there. Here's a springboard that would cover most of the wishes:
1. ethernet port.
2. RS-232 port.
3. analog D/A A/D port.
4. digital input/relay port.
Why?
1. Ethernet port would provide most of the high speed I/O you need. If you're using ISDN or DSL or whatever, you will need a terminal adaptor of some sort that's going to eat more power than a Visor can provide... so you need an external box with power anyway. So connect to it with Ethernet.
2. Serial port will work for the rest of the terminal adaptors you might need to drive, plus connect to all the hobby process control devices out there, your Basic Stamps, external IR units like the Lego Mindstorms control tower, and so on.
3. A/D and D/A for your diabetes test gear, your voltmeters, pocket oscilloscopes, and so on.
4. digital input for the rest of the control kit. Relay control rather than digital output because the visor hasn't got much battery power to drive external kit... with an external battery connector it becomes a digital output port as well.
How about it? The 'geekpack' springboard! I'd buy one!
