I wotk at two different places, meaning two different computers. Add to that the private laptop (mainly for FSFE FSCONS and GNU Xnee work) plus the family desktop. The sum is 4 computer which I use actively more or less on a day to day basis. The locally installed tools I use for communication are: icedove and pidgin.
Adding one person to your Address book or Buddy list to your computer means I have the person in one computer only. Remedy is version control, accessible over the net. So far I’ve been version controlling some of the files for pidgin. Worked out quite nice. Having added ‘robban’ I now decided to take the step to version control everything in pidgin, including the logs. After that follows icedove versioning. Let’s see how everything works out.
Wish there was a simple way to have you private PGP key easily available over the net 😉
