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.
Also for those not familiar with Linux BFG 4.7 does come in a windows version. I did install it and was able to point one of my S3's to my computer running it and it did connect and mine at Slush's pool. I am going to try it with a tube just as soon as it arrives but as FC advises BFG 4.7 will work I don't see a reason why the windows version 4.7 wouldn't work also. sidehack is going to try later if he has time with an actual tube. Check FC's thread post for updates.
