That's great to hear, Marcos! I'll look for it in the market 8-)

FWIW - I should have mentioned this before - I wouldn't recommend
requiring the use of ".localhost", just mention it as one option that
implementers might consider.  For devices with their own IPs or DNS
names, they should also have the option for using a more traditional
authority;

http://<device-name-or-ip>/widget-instance/c13c6f30-ce25-11e0-9572-0800200c9a66/index.html

And obviously, in those cases, whether access is opened up to those
widgets from outside the device is up to the implementers, carriers
(where relevant), or (where I hope we get to eventually) user-defined
access control policies.  But it does create some interesting
possibilities!

Mark.
