Hi Rick,

Thanks for the input. In a case where a fat client app (VFP) runs SQL statements over the Internet which might return large data sets would you say then that the SQL over HTTP mechanism you provide in Web Connect & wwIPStuff is a better way to go than web services?

If a Web Service sends back data that takes more than a second to convert into XML it's probably sending way too much data back for a distributed application.
