[Freedombox-discuss] Environmental limit how can we use this hardware?

[Rick]

It seems logical to continue developing for the dream plug and source other
devices.

The dream plug is a viable and available target for development, and useful
long term for environments that aren't hostile.

So we make an effort to research new targets, and perhaps ways to cool the
dreamplug (and future targets) that aren't expensive to build to expand the
useful temperature range.

The objections I've read are valid, and raise concerns about environmental
problems for a large segment of the target deployment.  That is done, I
suggest a focus on solutions.
