Exchange 2007. Not a desktop app, of course, but for some reason on every system i've tried it on it uses (amount of ram)+2gb, meaning the system is in a constant state of utilizing the page file. not nice.
Thats assets, what about recurring costs on the ISP side? If you have 30k subscribers @ 10mb each, you'd need over 300 OC-192 lines to keep up if each sub maxed out his bandwidth. I dont know how much one of those costs, but I'd love to try one out for a day...
We use APC PDUs to remotely control the hardware power to our servers and network devices. They have a nice web frontend, but i believe they have a telnet and maybe ssh too. It doesn't solve the issue of restarting programs, but i like them because they're completely independent of the hardware you're trying to restart. log in, check off the outlets youwant to control, give it a command (off, reboot, on) and click apply. 1U rack space and provides 8 controlled outlets.
