I thought you were talking linking up volunteer's machines via
residential broadband. If it's a local cluster, e.g. Myrinet will
set you back some 1 k$/node. That leaves you with 2 k$/node,
or 2 MBuck/1 kNode. Don't forget that you'd need 200 k$/year
for juice, minus air conditioning and admining (allow for
1 MBuck/year operational costs otherwise).

We already have those -- they're called silicon foundries, and
take multiple gigabucks to build and run.

Let's wait for desktop fabs, which will allow you to generate
dedicated hardware for neural emulation while being affordable
(0.1-1 M$). Maybe in another 25-30 years.
