Hi Gene

Assuming he is in a larger city or can get to one frequently:
Webcam for Skype for your wife
Small, portable, backpack size
Not too expensive due to theft issues?
Maybe iPad with rugged case and Bluetooth keyboard

Maybe a new cell phone bought in Peru or a mobile wifi.

The adventure of a lifetime. Camera might be most important.
