You can do this with a moderate sized enterprise. Engage HP/Dell or a strong VAR. Get them on the hook and focus on Intel E7 (and SQL Server enterprise if you are an MS shop).

Then get meeting scheduled with IBM and Oracle. Talk to the VAR or OEM guy in your office with your POWER mug poorly hidden. Start asking questions about TPC benchmarks and error correction. Ask if you can pay for cores only when you need peak capacity.

Intel will provide them with marketing support, potentially very significant if they care about you. Microsoft will also bend over backwards for an Oracle compete opportunity.
