FM Web limitation questions?

[iNovice]

1. Do the tabs layout feature in FM 8 advanced work with a web published database?

2. Since I can't seem to get any help in controlling access to data within the FM desktop application, is there a simple and secure way of downloading record data from a web solution and then importing that data into a mirrored desktop solution?

3. If I want to publish online Quicktime video files within individual records, what are the most critical components in serving those files properly.. (memory), (CPU), (harddrive), or (bandwidth)?

4. Does the 100 simultaneous user limitation (FM Server 8 Advanced), apply to each database file or all database files being served on an individual server? I was told that 100 simultaneous users really means 50 unless it is used in conjunction with Xserve. Is this accurate?

Is there a cost effective way of increasing the simultaneous user numbers?

Thanks for any help or suggestions!
