@hvmhvm The link doesn't work anymore, but I've got the Apple Configurator tool on my Mac as well. Thanks to your hint, I used it to install a WebClip payload to invoke a Pythonista script and it works like a champ. I can also install various icons and whatnot.
For me, this is a better solution.
Has anyone updated a version of OMZ's web-page that will allow one to upload icons? That's the only thing really missing.
