Neat. Are there any beefy-enough SPARC chips around to serve as builders
some day? If not, then at least we could get a wimpier one (OpenSPARC on an
FPGA?) and do like the wimpy ARM bots.

Oracle seems to have a pretty recent (2013) offering targeted at big iron,
and it seems pretty beefy <http://en.wikipedia.org/wiki/SPARC_T5>; the
linked white paper is talking about multi-socket x
16-core at 3.6GHzsuperscalar and N x 256GB DDR3. I didn't see any price
tag, but I'm
guessing that the people who actually need these sorts of big-iron machines
have (much) deeper pockets than we do........ (nonetheless, we have some
Oracle contributors, so maybe they could talk to the right people).
