Gonzalo,
I managed to get it running....
In domain.xml, replace 0.0.0.0 for a domain name like anahata.com
and then in your hosts file map anahata.com to the actual ip address of the network card. If you try mapping it to 127.0.0.1 then it wont work.
Our app-client launches over the internet now (takes a little while though)
If you need any more help you can write to me: pablo at anahatait.com
