> is there anyone using plan9 as their only system for development activities?
Not sure if this counts. I use plan9 at work though most of the code I write is for windows (server apps), Linux and embedded, so Plan9 becomes a glofified IDE for me. Having siad this it is an excellent IDE that is a pleasure to use. I also do occasional Plan9 development and maintain a port of some plan9 tools which allow me to do the equivilent of cpu(1) to a windows box. Wish I had more time for plan9 development. -Steve
