>In other words, you can't just say "USE http://www.myserver.com/data/customer.dbf". Certainly stop by http://www.west-wind.com for some other alternatives to reworking your app for use on the web.

Actually, you can, but not exactly like above. You can use a DBF with a UNC name:

USE //myserver.com/data/customer.dbf

The client machine just has to have permission to do it, and the server has to have the folder exposed via sharing.

The wisdom of USEing a table over a slow connection is another discussion altogether...
