If you're just using server CPUs, add my vote to mine LTC instead.
I do not want to have to talk to my boss about LTC after finally convincing him to give some Bitcoin investing a try. I think trying to raise funds to buy a few ASIC miners is the way I want to go. Is it necessary to go through an exchange like bitfunder or do you think I could raise funds on the forum for this?
How much can you offer for remote hosting? (Power available/space/cooling). With the unhousehold friendly BFL mini-rigs cost some people may be interested in hosting off-site if your fees/% take is reasonable. Something in the order of electrical + rent fee and 5% of mining proceeds to cover on-demand management. That's likely to be your lowest cost to generate worthwhile revenue but you need to be able to host and provide cooling for many units to truly entice most bosses I would think....
Alternately, LTC is ripe for sweeping up low cost gpu and generating very nice btc returns with trading, your still mining "for" btc but your using a platform that produces better ROI with lower costing last Gen BTC hardware.... that could be your sales pitch for LTC if you want to brave it....
