I was in touch with Rich Buchanan about this nearly a year ago - his reply is below. I was indeed asking about a device that would allow you to watch the TV stream. I'm sure that it can be done with a laptop and a scart lead, but my idea would be that a computer would not be required.

It would be similar to an analog telephone adapter, which allows you to make and receive internet calls without a computer, as it would link directly to the router/modem.

The Slingbox will be capable of remotely controlling set top boxes, but I think you were asking about watching [for example] US TV programming on a normal TV (a common expat desire and a common desire to connect a living room PVR to the bedroom TV). We have a product under development that will address this situation, but have not committed yet to a production schedule.
