no he should, if he wants for bitcoin to succeed. this could be what kills bitcoin. it would also not be good for Vladimir, if he crashed bitcoin after pumping alot of money in to it.

We already have a competing ASIC builder. Combine that with the various FPGA offerings and Butterfly Labs, Vladimir isn't posing a threat. I don't think the OP will get very far with this, anyway.
