>3. "The network is slow..." running 70+ users on dbf.
What is the average number of users per company network.

Should we switch to SQL because most companies have over 70? It seems that there is a lot more business (and room for innovation and [of course] new project sales) at companies with about 10 to 20 users. Lots of 200M$ to 700M$ companies are in the less than fifty range - and many of them - don't have (or desire) an IT department or DBA. It seems there is a lot of room for DBF solutions in these kinds of shops.
