still... you can't bridge the ppp adapter so it will have to be on its
own subnet that you masquerade or route appropriately.

That's a great idea Matt! Might be a drain on the battery moving packets 
around though. Speaking of which, would anyone know if it would be 
possible to use a 3G USB dongle on one of these? I can't see why not. I 
have a friend here in Australia who users a Three (Hutchinson) network 
USB dongle plugged into his Ubuntu box. He tells me it uses PPP to 
dialin and it's as easy as pie. Can anyone shed some light on this?

Cheers,
Nick

you can use a gta01 with a y-cable and power source (i modified the
hub below to provide 5v upstream to eliminate the need for a y cable).
I only had to add the modules "option" and "usbserial" to work with
the 3g adapter. it's a cdma/evdo adapter from verizon.

http://chockerblockablog.blogspot.com/2008/03/neo1973-no-wifi3gbattery-life-no.html

it's not too hard to make the neo act as a bluetooth access point to
multiple devices and also bt dun server for one more device. I haven't
set this up on the neo yet but I did do that with a gumstix.

i think it may still be up in the air how to run a usb device and keep
the freerunner charging externally. this 3g adapter i'm using draws a
lot of power, so it almost certainly won't work when only powered from
a freerunner's battery.

In ad-hoc network mode only. AFAIK the WiFi chip used in the Freerunner  
doesn't support AP mode.

Please someone correct me if I'm wrong, but I thought the WiFi chip in

its a firmware. the wifi module has its own firmware and does the 802.11
handling there autonomous.
that concept is called hardmac and was there earlier, e.g on the old
'orinoco silver' aka hermes pcmcia cards.

that firmware can currently do client mode and ad-hoc.
_in theory_ every wifi radio can do ap-mode, its just a question if you
can send packets at a low-enough layer in the right format.
this is controlled by firmware on the wifi module in this specific case.

=> ap mode would need another firmware which we do not have and not know
if it exists at all from atheros to be loaded into the wifi module.

so there is nothing we could do on the driver front to change that.

It's also a matter of receiving bulk packets efficiently and they don't
give us monitor mode either.

We're helpless unless Atheros decided to implement Master mode in their
closed firmware.  Unfortunately the power advantages of having the bulk
of the ieee80211 actions managed in the firmware are pretty compelling
so I don't know how we get out of that bind.

The very knowledge that we can't do something that the hardware would  
technically be capable of is annoying, but I don't really see why we would  
need to implement a true AP in the phone. For any reasonable use case I  
can think of, ad-hoc mode should be enough. The only usability advantage  
of being an AP would be that it can send beacon packets that allow other  
devices to detect an available network, but sending beacon would be a  
battery drain anyway.

Strongly agree. In some cases this was a result of the agreement we were 
able to reach with the chip manufacturer in order to open source the 
driver. We don't view this as a perfect solution, but rather a good 
start. Hopefully in the future the success of Openmoko will encourage 

Strongly disagree. Innovation is stifled whenever choices are limited 
simply because we can't think of why someone would want to make that 
choice. We should always strive to make such choices available.





Assuming the use case made sense, the Freerunner could be powered 
externally.
