Incognito is a control panel and system extension that allows you to bypass that annoying, network–based serial number protection that seems to be the Hot New Thing in copy protection. The theory is simple: when you buy a product, you get a serial number with the product that you enter the first time you start the program. The program then uses this serial number to register itself on the network, guaranteeing that there is only one copy of that particular program running.
While this is an admirable attempt by software publishers to preserve their sales, it becomes frustrating in the following situation: you have five licenced copies of Photoshop™, but ten machines. What happens if three copies of Photoshop™ are running, you try and launch one and that copy is already in use? Obviously, you don’t want to dump five copies of Photoshop™ on each machine, so you fire up file sharing, figure out which copy isn’t running, and copy it to your local machine. What a PITA.
With Incognito running, the situation is simplified. After setting up Incognito to mask your copies of Photoshop™, just launch any Photoshop™ and it will run. Then, install a licence–management system like KeyServer™ to insure you don’t exceed your licence and you’re golden.
Note that Incognito masks names on a single machine only. To be able to mask across a network effectively, Incognito and its associated prefs file should be installed on each machine. This is because each running copy of Photoshop will try and register the serial number; since the registration is machine–based, Incognito has to be machine–based also.
