That's a good question. Martin is right it's
a subset of the standard edition, it also contains a special
jLibrary connector plugin that of course only makes sense within
jLibrary. It makes it possible to switch very easily between
different local jLibrary repositories. There is practically no
configuration needed to switch between the this repositories.

I think I should explain a bit what I mean with a connector plugin:
The JCRBrowser is divided into three different kinds of plugins
o The connector plugins,
o the UI plugin
o and the API plugin.

The API is a simple Eclipse extension point that basically specifies
how to get a JCR repository and a JCR session.
The connector plugins expose their JCR repositories and sessions via
this API.
And finally the UI is developed to use the API to retrieve the JCR
repository and the JCR session.
This makes it possible to add new connectors quite easily and to use
only JCR classes in the UI without being dependent on a repository
implementation. I can use a lot of the pluggability power of Eclipse

At the moment I have three connector plugins. A special jLibrary 
connector, a connector for a local Jackrabbit repository and a
connector for a remote repository (via RMI).

The jLibrary edition contains:
o of course the jLibrary connector and
o the remote repository connector. The latter makes it possible to also
connect to remote jLibrary repositories.

The standard edition contains:
o also the remote repository connector
o but it additionally has the connector for local Jackrabbit repositories

If you want, you can even put all connectors together in an own edition.
It will work without problems. I just seperated them to avoid confusing
either the jLibrary users with the local Jackrabbit connection in the
preferences or the users that don't use jLibrary with a jLibrary
connection method.

Quite a long story but now you also know the simple architecture
with the three component types.

Yes I know it would be nice. I already think about to create such a tool 
  and I have a good idea how to easily create the business logic and how 
to be able to easily maintain the business logic (I don't have a prove
of concept yet). But I also know that it will need a lot of effort 
anyway and it's prio 2 after getting the JCRBrowser final...
