From the license agreement: CachemanXP has two types of licenses: Workstation and Site. The Workstation license is a one or multi computer license, the amount being selectable at purchase time. The Site License is a multi-computer license that allows usage of the program in the registered mode by all members of the company (team, group, and etc), which owns it. If you decide not to purchase the full version of CachemanXP you are allowed to use the unregistered shareware version for an unlimited time. Also, according to the help file that came with it there are a couple of added tweaks if you register it along with support, which you don't get unless it's registered. So the "unregistered shareware" version is free to use in an unlimited fashion. I've been using it for ages and it works. :)

You're already falling
It's calling you on to face the music.
