I do a mix of part-time sporadic things in the academic / non-profit arenas.
1. 100% on-site, no telecommuting, but in Hawaii.

2. 100% on-site, no telecommuting, but in Hawaii.

3. 100% on-site, locations all over the world (thus all the flying)
4. 90% on-site, rare telecommuting, but in Hawaii.

5. 0% on-site, web+email+IM+VNC broadband access needed.
7. 0% on-site, web+email access needed.
6. 0% on-site, web+email access needed.
I keep meaning to simplify, scale just a few up to the point where I can live of 'em and drop the others... but it's so much fun.
