The netflix box is new hardware - and there doesn't seem to be much 
reason for promotional pricing.  They claim that they will release an 
SDK soon for anyone who wants to generate their own channel (but not 
opensource the box itself).  But as long as you can send some 
standard-protocol stream, why worry about matching the hardware?  A sip 
speakerphone might even work as an endpoint.

Here's an interview with the roku CEO:

The chumby is probably more hackable, but it already plays network streams.
