Thanks for all the feedback, sounds good - but of course like most Apple stuff, limited in some areas compared to open source solutions.
I also have
AirServer App, which compares itself with Apple TV.
I bought it for work, so I can mirror my iPad to my laptop for WebEx demos of products on my iPad. But looks like it could be an alternative too - would just mean connecting my laptop up to my TV, which I can't really do right now.
