Sky has launched Sky Stream, a streaming box which looks similar to VM's Stream. One difference is that Sky Stream will work with any ISP's broadband, unlike Stream which only works with VM's broadband.
Must say this looks interesting. There is a monthly fee but includes Netflix and the ability to add Sky add-ons on a monthly basis just like NOWTv stick. I might try this on second tv and then consider replacing my current VM tv package at end of contract for main tv. I have seen a working comparison with VM Stream and it does seem to run more smoothly and with a better fully integrated guide.
