Nice! One thing I would like to see is some way to reserve names so that only I can use them – right now if I'm publishing data to http://dweet.io/follow/outdoors , anyone can easily override that with http://dweet.io/dweet/for/outdoors?no=temp&for=you - so that'd be a neat feature. Unless the idea is that handles would be shared between devices...

BTW, I'm dweeting that outdoor temperature using SmartThings and this code - https://gist.github.com/alexking/8880479
