On how many websites can I use the pro-version?

There is no limit. Use it on as many sites as you like.

Is the pro-version encrypted?


Does the pro-version need Ioncube?


Is there a trial-version available?

No. You can try the free version. It shows in red which functionality would work in the pro version. Which will give you a pretty good idea of how this could work on your site.

Joomla 2.5 has some ACL. Why use Access-Manager?

1. so you can set rights on groups instead of levels.

2. so you can reverse rights (selection has NO access)

3. Because in Joomla you can still only assign access to only ONE accesslevel per article/module/menu-item/etc. not multiple. You can create custom accesslevels, sure, but its a nightmare for schools and universities where the users are students and the groups are the courses they take. If there are 20 courses and each student takes on avarage 5 courses you need to make access-levels for EACH COMBINATION of groups. 1-2, 1-3, 1-4 etc. 2-3, 2-4, 2-5 etc. 1-2-3, 1-2-4, 1-2-5 etc. You get the picture, that is 100+ accesslevels, that is totally unworkable. And you would still need double content, which is a nightmare for administrators and users.
In Access-Manager you can set access to as many groups (or levels) as you like. So in the above case you would need only 20 groups.

4. To do ACL stuff that is not in the Joomla core (yet).

5. Access-Manager can set custom actions if the user has no access.

6. Joomla usergroups ALWAYS inherit rights, which can be a pain in the rear, in Access-Manager groups don't inherit, so you are in control.

What is the difference between Access-manager and Frontend-User-Access?

Access-Manager overrides the Joomla accesslevels, FUA does not.
FUA only restricts the viewing of content. To view content, the user needs Joomla viewing access. FUA thus creates an extra viewing-access-level underneath the Joomla levels, whereas Access-Manager overrides the Joomla accesslevels.

Access-Manager uses native Joomla usergroups and accesslevels.
FUA uses its own FUA-usergroups.
