I've now tried this on small scale with bitcoinplus running on 3 computers over the night. It generated a total of 0.0110132 BTC. Probably won't try it with all 40 computer as it seems to be quite a hassle.
theft is theft
What would I be stealing? Who's losing anything? As I said, the computers are used for rendering 3d graphics occasionally anyway, and then they're also using the schools render farm. So bitcoin mining is actually using less electricity than usually.
To be honest, I don't even think the IT technicians at the uni would mind. I know one of them who's involved in the Pirate Party, and pretty open to new innovative ideas. I'd be surprised if he haven't tried this himself.
Over night for 3 computers generating 0.01BTC is scalable if you could cut down some of the waste in the process. For example, if you made a good revisor image and could quickly boot all of the computers, that scales to 0.4BTC per 10 to 12 hour period (depending on campus hours). That's possibly 0.4BTC per night for 7 nights = 2.8BTC x 4 (month) = ~8BTC.
If you could reduce the waste (setting up PCs, etc) and streamline it or include other individuals to assist (maybe you could split with one of the IT admins?) you would have a constant trickle of coins.
Even better - if your IT staff is as "interesting" as you say, perhaps you could set up your own individual pool or convince them to upgrade GPUs. In most cases, I'm sure the students would be particularly enthused to see cards capable of faster rendering (you said you had students using the machines to render, right?).
And for whoever said I was delusional about whatever... If any of you believe that BTC is an officially usable and measurable asset *at this point in time*.... I'm not the delusional one.
You could very well use the project in purely academia and never exchange the coins.
For an analogy - is the school entitled to coins someone earns playing WoW on their personal laptop that is connected to the schools WiFi? Some schools sponsor a "game night" where users can install and play games on the PCs - what if they play WoW on the network on a school owned PC? Are you stealing resources for an asset that *might be* exchanged for cash? What government agency/school/university is going to attempt to sue all of the WoW players because that entity is entitled to a virtual currency the player earned in-game as a result of using that entity's resources?
Surely WoW assets have an extremely larger liquidity market.
