I could not agree more. There is no more need to solder the boards
ourselves than there is to etch them in our bathtubs.

Again agreed. Also look at:
Which is company that has released a couple of SPARC compliant cores.
They have been put into real products and into space. The rad hardened
versions (ECC, etc.) are not free, but they may allow us to use them in
return for space performance data.
