Actually, I think this is something severely lacking from the Sling website, looking at it from a pre-sales perspective.

What they should have is some example feeds available for use with the Sling Player, at various bit rates. So there'd be a link for a 256kps feed, a 288kps feed, 315kps, and up through the possible upstream possibilities.

Sling wouldn't need to have any copyrighted material being broadcast, they could just have a sales video or some such blurb on a loop. Perhaps this sales blurb could have some example footage, ie. a sports game, some people talking, so as we can get an idea of what the different genres of TV programmes look like when Slung.

The SlingCommunity Team would like to remind the Community that the End User License Agreement states that it is a violation to share a Finder ID, or allow access to anyone who does not reside in the same residence as the Slingbox. To avoid violating this agreement, we suggest that those who wish to test view the Slingbox do so at a local electronics store or in the company of the Slingbox owner. Sling Media is in the process of working on a demo which will allow users to "test-drive" the Slingbox; availability will be announced at SlingCommunity.com.
