Nice!
I worked for several years for one company as an on-site tech — for another company, both of which required me to use their stupidly locked-down corporate laptops. While these machines may have worked well enough for rank-and-file spreadsheet jockeys, they locked after a frustratingly short period of inactivity as I bounced back-and-forth between ten or so computers.
My solution was a tiny homebrew Caffeine workalike which slept quietly in the background most of the time. occasionally waking up to either move the mouse pointer just one pixel, or to “press” a normally unused/unavailable/unassigned function key like F24.
(For my own work, which required software that neither corporate bureaucracy supported, I brought in my own netbook to avoid jumping through two sets of corporate IT hoops. My office was generally left alone, so I kept my machine off company networks and all was good, or at least productive.)
