[net2-wg] Proposal for dissemination structure and interfaces

[henri dubois-ferriere]

i'm not sure that future platforms are "10k and up". I think some may
be 10k and down - there are quite a few MCUs (MSP430 included) which
have low-RAM versions (512b, 1k, 2k) that are significantly cheaper.
If/when any platform is ever produced at large scale, those MCUs (or
single-chip solutions) are not unlikely to make a comeback.
