I don't know how well it will scale having a header file with 200 domains. At the same time 5000 users is not out of the question for phpgw. As they will be broken up into domains the scaling issues should be reduced as you aren't doing look ups for 1000s of users. > I'm afraid, not...

Have 2 or 3 front end "sets" and a matching number of db boxes. You haven't mentioned how many concurrent users you are planning to expect so I can't give you a more specific solution. I am happy to try and assist you with this implementation, in my spare time (which is rather limited atm).
