FYI I had don't some research on these a while back...keep in mind these are DEVELOPMENT boards...they have alot of crap on them that is not needed for a straight mining board. I did preliminary work on stripping all this stuff and beefing up the power/cooling for higher clocks. Don't know why you would build/buy these in their current state for mining.
Fair - something senseless should consider. However pin compatibility from a second source would be great.
@senseless - Yes Ive got my own RTL and bitstreams - as well as some of my own hardware. Im pondering your shell/publishing concept, but I havent decided if it makes sense yet. I can see the VCU1525 and derivatives being produced in much greater quantity once there is interest though, and that leads to price reductions and makes it difficult for other options to be competitive.
