Haystack, OpenTag, Dash7 - a possible start on the Internet of Things. Also, MangOH

Sierra Wireless offers IoT Connectors on the MangOH

and that looks like another nice Linux platform.
Somewhat more ambitious is Dash7. Apparently the guys behind it have sold large numbers to defense buyers already.

Apparently this is dominated, if not entirely controlled,by just one corp:
http://haystacktechnologies.com/
http://haystacktechnologies.com/_dev/products-and-services/hdf-1-0/
and they have a particular product ... but the links appear to be dead.
However, they have some working slides from 2012:

http://www.slideshare.net/MaartenWeyn1/dash7-alliance-protocol-technical-presentation
http://www.slideshare.net/jpnorair/introduction-to-dash7-technology-1698125
and if I understand this rightly, they promise that the IoT built with their magic will be spiderable:

I like the looks of Dash7. It looks better than this:

I like the promise that it can support crypto:

Multihop rooftop meshnets look pretty cool.
