The only limitation of unlimited version your address IP (public IP).
You can run as many WRobot you want to as many computers as you want at the same time if you use same IP address.
If you start WRobot on another internet connection (IP), WRobot running on the first IP will be closed.
I do ALL of these things as well and I have no problems. Buy the unlimited account. It works great. I installed my wRobot into dropbox. The only complaint I have is when I open it on another computer the serial key is all jacked up so I have to enter it in. Only happens the first time I open on a new computer. It then saves the serial key and on other computers it LOOKS jacked up but is functional. No biggie really. Probably something to do w/ dropbox.
I have usually 3-6 accounts running on my system at once. I have had friends over during LAN's that use wRobot as well and they run it fine from my IP though most of us use some kind of proxy or VPN to hide ourselves when we can...just to be safe for botting.
