I can tell you about possibilities using my own example - in my company we are using Calipso as a CMS for a aggregation of spatial web-services, basically Calipso can do this:
Admin / client panel
Roles and multi-level access control
Theming
Code is readable and pretty easy-to-modify (especially when you are used to asynchronous JS execution)
Hi. All
it is not explicitly described what I can do with calipso.
Is there admin panel and user administration module?
