Straight forward install or non install.
Can be deployed very quickly and without much hassle.
Noticed that with vista and win7 it tends to lockup requiring a reboot before it will work again.
Dose not work with some programs on the remotely access computer.
Zone alarm is the first I was able to verify that dose not work on remote access.
Great for home networks,
If the commercial version is the same thing as the free version, then do not use it in a work environment until the stability and compatibility issues are resolved.
