One idea I had was having the ability to create profiles for each type of distributed project that I could assign hosts to.

For example, I would create the following profiles (Science, Life Science, Mathematics... etc) and assign projects and hosts to each profile.

Then when I felt like switching from Life Science to Science, I could point the account manager to that profile and have it update all my hosts. (Assuming I finished all my work in the current profile of course).

...Just a thought!
