Why the Web?

I would do it for the same reason that anything ends up on the Web;

- I can manipulate it from the same app I use to manipulate so much of
my life already; the browser
- it can leverage existing and yet-to-be-developed extensions such as
WebDAV so that access to it can be locked, versioned, etc..
- if I forget its URL, Google can find it for me
- if my house network is unreliable, an existing cache on the network
can let me know what the last cached state of my thermostat is, and
when that state snapshot was taken
- authentication for free
- content negotiation permits my french-speaking serviceman to
also manipulate and debug it remotely through the same URL


If that isn't reason enough for you, then do it just to prevent the
APPS area from needing 10 area directors by the end of the decade. 8-)

You didn't think my explanation of reliability in the context of
thermostat control was sufficient?  Can you elaborate on what else
you'd think would be needed?
