Domino Collaboration Express license restrictions. Why some restrictions?

I read from IBM:"Consistent with the needs of smaller enterprises, license restrictions are in place that remove Domino elements and attributes appropriate only to larger enterprises. Thus, the following attributes are not included in the Collaboration Express license:

→ Partitioning or clustering – these enterprise requirements don’t apply to implementations of fewer than 1,000 users

→ WebSphere Application Server (WAS) entitlement that’s part of standard Domino – ->WAS Express is available separately for this segment

→ IBM Lotus Domino Designer – may be purchased separately, but typically IBM business partners would supply custom applications

→ zSeries (including zSeries Linux) platform use – all other Domino platforms (Windows, Linux [Intel], OS/400, AIX, Solaris) are entitled

In addition, certain administration functions are restricted by license:

→ Extended Access Control Lists

→ Cascading directories

→ Directory catalogs

→ Directory assistance

→ Central directory (userless Name and Address Book) "

Why?

Why cascading directories?

Why directory catalogs?

Why directory assistance?

Ok, other from this restrictions (like partitioning) are OK.

But why directory catalogs?

In directory catalogs you don’t have all documents about databases server?

What are cascading directories? Because i don’t realize that is cascading directories…

Thanks for your help!

no replay?may be from IBM Stuff?

Subject: Differences…

A directory catalog is useful for mobile users if your Domino Directory is growing large. Express is intended for small companies, up to 1000 users I think. IBM probably thinks that a directory with 1000 users isn’t going to be very large anyway, so why bother with the directory catalog? Same thing probably goes for cascading Address Books: not really neccessary for smaller companies. IBM has to make a difference functionality-wise between normal licenses and express licenses, so they stripped out these features, that a small company probably wouldn’t use anyway.
