So, did you have any success in the end? As a seller, you have to be very patient at the moment until BitWrk's eco system has grown bigger. We need buyers mostly, so this is a call to all the Blender enthusiasts who also happen to a have some (milli-)Bitcoins to spend.
I don't think there is a cheaper commercial rendering service for Blender at the moment.
No, I am pretty sure I fixed the issues with the VM and my ISP and that the port was open though. I will give it another try later tonight.
