Hello, yes there are quite a few.
Some of the guys are producing decent 5/6ghash's setups. I know of a few that have ASICS etc. Its def happening to a degree.
Im just running my 6990 at 700mhz giving me about 750mhahs but being nice and quiet while doing it.
Oh and i dont pay for electricity
Before the big drop $0.1 per BTC, i was running a setup with 2x5970's and a ASUS Ares and was getting about 2Ghash. Then i was earning about 5 BTC daily. Then the crash and sold everything... How i wish i had had some foresight and kept mining
Also working on a few bitcoin projects. I have Safe Wallet that is available here somewhere (source code included) but am in progress with a few friends starting a much much bigger project.
Hope it works out
