10 000 CPUs at ~5 MH/s (and this is VERY optimistic!) = 50 GH/s. Would be a barely noticable fluctuation in the current hashrate.

~5MH/s is very doable with Ufasoft's SSE2 CPU Miner.

A Core2 Duo 2.2Ghz gets ~5MH/s.

It is very possible that we had a botnet come online. Not very difficult to find a nice sized (30K - 50K) botnet these days.

If I helped you in some way, and you feel obligated to do so, you can tip me some coin!

The botnet operator just needs to install the UFASOFT SSE2 miner and tadaaa...instant hashing monster. Assuming he could somehow select for intel i7 or intel SSE2 capable CPU and he can get 12 - 18 Mhash from quad core chips (this is for intel i7 - 12 Mhash is easily achievable even with 3 cores)

Mining botnets?

Can you see how useful bitcoin is for people! We actually will improve security of residential computers en masse. This is because now hapless users will have much better chance to notice that something is wrong with their computer and it eats CPU and electricity. Thus they will secure it.

I wrote a script to use Ufasoft's miner silently in the background only when no user was logged into a PC (state=Inactive).

I'm a network admin for about 2,000 PCs. I wouldn't run it on them, but I verified I was getting 10 MH/sec for the model we currently use. So yes, I think if someone had 10k PCs and could pull 10 MH/sec on each or push out the latest ATI drivers to the machines that had video cards for a university lab you could see this happening pretty quickly.

I would like to imagine the maintenance guys at universities and other public institutions would catch on to this sort of thing, though. In a corporate environment I would imagine it would be nearly impossible to do.

That being said, I could imagine a lot of gaming studios with high-end PCs maybe having some sys admins pitching the idea of running a Bitcoin network to their bosses.

Yes, and rendering farms. Animation studios and ancillaries have large GPU resources ... not sure if they Nvidia based or ATI. Although they probably keep them pretty busy making flics.

useful indeed.

by 2030 or so we may have brought 30-40% of the population of the world into the 21st century.  which is a helluva lot better than we did with the 20th, by the time 1930 rolled around - and people were still emulating ancient roman emperors bringing in massive blocks of ice to cool their homes and food (while electric light bulbs dangled from their ceilings).

the power of money...

check out this diagramm: http://bitcoin.atspace.com/mysteryminer.html
I just found it with google. probably from Raulo. I will pm him to explain how he gets the data.

very interesting. at ~400GHash/s it was more then half the network power for a short time.

Yes, it was. The graph was made by analyzing activity for this wallet

Follow the trail and see here it all sits .... 49,000 BTC

http://blockexplorer.com/address/1JYdudjausg1VUzosifETZbuLAevyPgnza

some days in late Feb. early March he was getting easily 50% .... what about those early adopters eh?

Wonder what he had access to? Server farm, botnet, super-computer, render farm? ... the way the block rewards are collated into chunks may reveal something.
