I agree that live rock from the ocean, under the best of circumstances, is superior; however, so much of the "live" component of live rock that comes from the ocean is lost by the time it finds its way into our tanks, that I daresay the alternative, cultivating your own rock, is a viable option.
The key is seeding, and not with a dead shrimp carcass. Getting well established live rock from another tank, or even buying a few pieces of live rock is your best bet. Seeding and replenishing is always a good thing to keep in mind, especially for a reef tank. Its not something done only at setup, but is an ongoing process for the life your system. By seeding and replenishing, you will ensure that your tank is teaming with beneficial and diverse life forms that support your efforts to create a natural filtration system in your tank.
