I drawterm all the time. Lately I have started using 9vx for quick hacks and then cpu from it to wherever I want to go. It has its quirks (not as stable as drawterm) but I'm not complaining.
With drawterm being so solid and well integrated with X11/OSX I haven't had the need to dedicate a terminal to Plan 9 since 2005. If I need to spend a relaxing day at work I simply fire dt full-screen and look at the colors :) So, I guess that means venti+fossil+cpu on one headless machine in some forgotten corner of the datacentre. andrey
