If they make it available to large companies and academic institutions to run on a local server, I would expect a lot of takeup. However Microchip's track record of running individual session based web services isn't at all good. Just look at the clusterf--k they've made of their forum for the last five years!
Here's a litany of recent Microchip software disasters as if we needed reminding...
o MPLAB X - launched in Oct 2011, it took four years to be what I'd call production ready.
o Harmony - launched in Nov 2013, that took two years before you could even start to do anything serious with it.
o Microchip Code Configurator - like Harmony, another sh!tty code generator to create untrustworthy source code.
o Forum - took about six months to settle down, and it's still sh!te. A solution looking for a problem if ever there was one.
At least the responsive* website released in the past week or so seems to work, although it appears to be the previous site layout with a re-chrome. At least it's not broken like the forum was for months.
And, the MPLAB Xpress UI does at least seem to work... apart from the bolt-on Java nonsense!
*responsive: when I first heard that term a year or so ago I though it meant it was going to be fast. Err... no, that's not what it means.
