I was just wondering if anyone has tried Tropo with Warp?

I have just started to look at it but it appears promising. Tropo is basically being hosted services with a programming interface. https://www.tropo.com/home.jsp

But it also works with Asterisk AGI. http://blog.tropo.com/2010/10/08/ast...sion-dialplan/

I was a little worried about firewall issues but it seems this has also been covered. http://blog.tropo.com/2010/02/24/usi...l-with-tunnlr/

My real goal is to try and use this to provide TTS services on a Warp. I was just wondering if anyone had any experience with this technology before I embark.
