An update on this project. I had a phone call with Telecom last week and got this official report:
"We have selected a couple of partners to work with at this stage for our crowd-sourced gateway. We’re waiting for test units to arrive and will give another update once we have some timings to share."
Basically the project is still alive and from previous conversations Telecom got to the point where a couple of features weren't included because the OEM's roadmaps included them for later, so adding now would be extra cost for nothing really.
The feature list continues as specified in the previous update. There's still the intent to have a Telecom-supported version of the gateway and a community-led, open sourced firmware project.
The test units are being sourced and soon after Telecom gives the OK for those we will have some to distribute around as part of the project. As per the update this will be in the next update.
