Ciao Davide, thank you for your reply. I use .NET as programming environment, and I've been able to create an output response stream with the correct MIME type; I'm sure that the size and the number of features are inside the allowed limits, since at this stage I'm just making simple tests. However, I don't know how to use this response in the KML Layer constructor... In mi .NET application I have an HTTPHandler which retrieves desired data from db, creates the KML string and sends back the response with the correct MIME type... Should I put the HTTPHandler path as URL in the constructor parameter? I tried that, but with no success... I also tried retrieving the KML string as return value of a jQuery ajax callback, and then passing that to the KML Layer constructor, again without success... Yes, I'm thinking about using Fusion Tables, however, if possible, I'd like to go on with this approach... ciao
