What Can You Do w/ 170,000 DirecTV DSL Gateways?

An anonymous reader asks: "I'm sure everyone here is already aware of the impending demise of DirecTV DSL. The latest twist is that, apparently, they're not going to want subs to return the DSL gateways, at least that's the buzz in the DSL Reports DirecTV DSL forum. If true, this means that we'll have around 170,000 of these things floating around, just begging to live again in some other capacity. So, what can be done with them? Seems a shame to let such neat little boxes go to waste. Does anyone care to come up with some creative ideas on how to hack them and make them do something useful?"
