I have certainly thought that having a similarly open lower-power
device would be a good thing (TM). We are involved in a project right
now where balloon3 is probably overkill and something like this would
probably suffice.
Perhaps the only problem is finding sufficient software-fettling
resource to support it. We have observed that without someone with
some money to spend to actually make things happen, then progress can
be very slow. The kernel suport for this chip is already good, which
helps (it's been around a while already - how much longer will it
remain available?)
But yes - go for it.
Wookey
