Yes; eventually. In small increments, by whatever spare cash chunks
happen to be around. Which is why high-power servers and blades
are out of question.

I'm not sure, it's hard to argue with 80+ servers in a single easily cooled rack,
with full IPMI and starting at 400+ EUR at a functional server.
On a larger scale I'd probably just use the naked motherboards (200 EUR sans RAM)
in custom trays, and with shared PSUs. In principle you can boot them
from USB thumbdrives and/or network.

I'm hoping that Supermicro or similar vendors will eventually offer ARM
based equivalents of http://www.supermicro.com/products/motherboard/ATOM/ICH9/X7SPA.cfm?typ=H&IPMI=Y
