Been there, done that. (see below)

Sorry, I should have included that info in the initial post. You're
right in that most of these tables have a similar structure. But they
are independent and can be customized by the users.
Think of it this way: On the server there are 500 applications, and each
has 30 tables. One of these might be a table which contains the products
of a webshop, another contains news items which are displayed on the
website etc. etc..
The problem is that the customers can freely change the tables ... add
columns, remove columns, change column types etc.. So I cannot use
system wide tables with a key column.
