I've been exchanging email with the folks at SlingMedia for a while about why there isn't a Slingplayer Mobile Client available in the UK....
Strangely the US Version works perfectly (as long as you can convince a US Colleague to buy it for you)
Well great news! They've released a version of their client for the UK for Windows Mobile!
If you haven't seen it before - SlingPlayer takes any output and rebroadcasts it via the Internet to your PC or Device!
