>Now, I´m starting to study ASP.NET, and I´d like too know how I can make such integration... is there any comments and/or material about that?

It works like champ! Create your data intensive web services in VFP as COM+ objects. Use ASP.net for your thin client in what ever language you prefer, I prefer C#. Add a web reference in your ASP.net project to the web service WDSL, and you can work with your web service just like it was a native object. I'm very happy with this combination.
