Looks like a promising CMT but...

1. It does not manage multi -categories which is really bad thing. Imagine a Restaurant with several sites, or a small group of companies with several activities
2. The encryption strategy is wrong-->Encrypt admin so that with no autorized access key the user cannot do anything (cannot activate nor configure the CMT), but let all Front End file available for customisation. In an open source environment being dependant of your good will/resources is an important negative aspect

Good start anyway.
