Yea that won't be a problem. The network is huge, even with massive production of ASICS it won't reach 51% and even if it would, they would have no incentive to attack the system as their whole investment is based on the Bitcoins they mine and that they can sell them off to make a profit. If they each 51% I suggest mining a p2pool.

Thanks for answering when I was away. Yes, we are part of the Bitcoin world and rely on the security of Bitcoin to succeed. And if we ever reach 51%, we could use p2pool, or scatter our hashrates to different mining pools with explicit names like ASICMINER, and hence make the statistics public to all people who are concerned.
