Do you love Emacs (or Jed) and you have a Palm PDA or a Treo 650 or something else cool that runs Palm OS; then you're in luck: install pssh
pssh is a SSH client for Palm OS that makes it possible to log in to a server running a SSH daemon and obviously the server will have Emacs.
Haven't had the time to install it myself yet but I will I hope. The only problem for me is that I don't have a WiFi card for my Treo so I'll have to try this stuff via GPRS which sucks.
