friedcat updated his post to include info on how to use bfgminer as a proxy then connect to any pool of your choice.
I have some spare Pis on hand. anyone who wishes to add a Pi to their order, let me know.
link please?
In the post after that I posted a solution ckolivas worked up for me using his own proxy software, which runs linux native. I haven't fully tested its limitations yet, and I haven't tested BFG proxy at all, but once I get the rest of these tubes assembled I'll do some more work on both options and post results.
