Some of us here did some Sat>IP research several weeks ago with a Mini HD SE which led to the development of a Windows based Sat>IP client.This does exist, see en.wikipedia.org/wiki/Sat-IP
This is the protocol used by the receivers that support streaming to an android device with ALi Big2Small or Amiko Streamer apps installed. The A3 does it, X2 premium III does it, and I'm sure there are more receivers that can serve a Sat>IP stream. There are also LNBs with ethernet ports on them which directly serve the streams as well.
The only LNB with built-in Sat>IP that I know of is the Inverto 5048.
At approx. $400 US, it doesn't seem worth it to me. Are there cheaper IP enabled LNBs available?
