Thanks for your kind words, and indeed we are building a "conversation platform" where those conversations can occur within and across whatever conversation channels are most appropriate.

One point of clarification – the difference between the Tropo platform and the IMified platform is a bit more subtle. With Tropo, you write your app in one of the supported programming languages and that file is stored either on your web server or up in Voxeo's hosted environment. However, the application is executed in our hosted infrastructure. We retrieve your Ruby program, for instance, from a web server (yours or ours) and execute it on our server cloud. It's really the same model as Google App Engine.

With IMified, the platform communicates with your application via HTTP. The execution of your application happens on your webserver (which could be on your premise or in some hosting environment). The IM connection comes into IMified, which connects to your application via HTTP and passes along what was received in IM, your application sends back via HTTP what should be passed back to the user via IM – and the exchange continues in that way.

So the subtlety is in where the execution of the application occurs.

Thanks again for your kind words,

Dan
