>We could store our clasfiles, since they are just actually vfp tables, in or as sql server files to be checked everytime a user logs on. When an update on the class file is present, the new classfile are download to the user, or if a new app is present, it is downloaded etc.

That's a clever idea, and wouldn't be hard to implement. But what advantage does this give over just copying the VCX from a designated network share? Now, I'm all for Microsoft selling more licenses for SQL Server <g>, but this seems like an expensive storage mechanism to me.
