This is cool stuff. But, what we really need for this to be done on _open_
platforms is for someone to code up a Bluetooth 4.0 alternate-PHY thing for
some open source operating system that lets one glue the BT and wifi stacks
together so they can dump data where appropriate.
Now, for the real feedback:
* bluetooth is lower power and shorter range, but it's also much lower
throughput (compared to 11n) for the same range to an adjacent device;
* it overlaps the whole 2ghz range, so if you're doing a lot of bluetooth
transmit, you're interfering with nearby 2ghz wifi devices;
* it also will be an "or" with the onboard wifi - ie, you can't transmit
bluetooth and 2ghz wifi simultaneously on a lot of chips. There's an
antenna switch that stops you from doing this;
* almost none of the open source stuff has sane transmit power or rate
control hooks that would let you get away with much higher density 2ghz
meshing - why transmit at full power if you're only talking to someone 3ft
away?
I like what you're doing but a lot of what you're doing is tucked away in
closed source blobs. It's hard to implement that on more open platforms.
Once people here get their (atheros!) mesh hardware doing much more useful
things, I'm happy to sit down and do more brainstorming in relation to what
you can do with the hardware and how you can do evil things at the 802.11
layer.

For those of you who haven't heard the news from
Jenny, yet: Open Garden
decided to publicly release the original white paper "Multi-hop Wi-Fi
Offload <https://opengarden.com/Multi-hop_Wi-Fi_Offload.pdf>" by CTO,
Stanislav Shalunov.
Hopefully this brings some inspiration and answers some questions (ex.
Mitar: Why Bluetooth?)
Also, please excuse my lack of participation this past month - I'll be
back in the action next month. I'm also going to a festival called
Libertopia <http://libertopia.org> this weekend in San Diego where I'll
attempt to spread the word. These people are really into alternative,
decentralized services.
I'm starting my drive down tonight so have a great meeting and enjoy the
weekend everyone!
Peace.
