I'm definitely interested, and will be able to put some serious cycles to the effort starting in 3-4 months. I'll circle back to chat with you more before then to get things going. In the mean time, I hope you don't mind having some discussions about the new stack architecture and TEP 126 as I come up to speed a bit further on the design. Over the next 2-3 months, I need to implement a star network where 99.5% of all packets travel from node to gateway and the latency of packets from the gateway to node can be rather long. I'm thinking a strategy as is used in 802.15.4 proper is the way to go in this case for minimal energy consumption at the nodes (the gateway will always be mains powered): that is, using the frames pending bit and implementing a node->gateway data request message. In my early looks at the cc2420_lpl stack, it looks like it may be possible to implement a different low power listening layer to do this. Am I on the right track with my thinking and research?
