Received an email to participate in a survey half an hour or so back.
Turns out it's essentially about making previews of shows coming up on SoHo available on iSky for a bit.
Wasn't of particular interest to me but I was pleased to see a free-text entry box at the end to say what you'd like 'iSky to be'.

So if you get the invite and you have some views on iSky here's the chance to spill your guts.
