So, this is cool.    Mike Hall, did a great job at introducing this technology at MEDC,  however strangely the press didn't pick it up.

Seeing the video again.  I have to say again 'WOW',  small low powered devices announcing themselves to your home network and exposing an API via web services.    Video at -

Imagine buying a washing machine with no front buttons but magically your fridge mounted flat-screen presents a beautiful touch screen control panel for every wash you're likely to need...

The documentation on MSDN is a little C++ and hardware focused (IMHO) ,  at - https://msdn2.microsoft.com/en-us/library/bb410236.aspx

I've often needed to control devices remotely like weighbridge's, pressure testers and other line of business hardware   WSFD could make my life much easier.

I wonder how long it will be before we can implement this all from the Compact Framework?  I feel a pet project coming on to implement calling web-services on devices myself (however the auto-discovery and stuff looks a bit tricky)
