My latest reply from Echostar (who own Sling Media!!) regarding the Boxee app for the HDS 600RS.....So crazy they behave as if they are separate companies!!Thank you for sending your query concerning your EchoStar SlingLoaded® HDS-600RS.
We would love to have this extra feature, however there is currently no support/plans of adding this Boxee SlingPlayer app with the HDS-600RS. We will forward your request to our technical department for review.
New software versions will be communicated via our website: www.myechostar.com/support , so we would ask that you look here for future updates.
We hope above information will be of service to you.
Very best regards,
EchoStar Support Team
