KMRemoteControl 1.5
KMRemoteControl is a nice little cross-platform program that automates some things you could do for free if you put enough elbow grease into it, but it does it nicely and I've been a long time user and fan. Better yet, there is a new Tiger compatible version, version 1.5.
I installed a copy of this program on my Powerbook and on the two systems I manage with my Powerbook, a G5 tower and a Windows 2000 Server, and any time I need to access one of those two computers, I simply launch KMRemoteControl and via a simply key combination, I can use my Powerbook's keyboard and mouse to control either computer. Nice. $24.95 for a two computer license. Check it out.
