According to their website it looks quite early stage/small scale/experimental. Anybody know how far from feasible and commercial scale they are?

In the case of the OP, even they are at least 5 to 6 years out according to the founders.

Last summer LightSail announced they had completed a full-pressure test of their containment structure at 200 atmospheres. [1] And Danielle Fong tweeted that their pressure tank survived the 'gunfire test'.[2]

The last update I saw showed complete cycle pilot tests in 2015 with deliveries to customers EOY 2015 / early 2016. They should be to market much faster than the OP version since LightSail is working on ~.5MW - 1MW installations and OP is working on much larger versions.
