This article (warning: pdf) from Tissue Engineering suggests that vat-grown meat may become actually feasible for human consumption.

There's an organization set up now to promote the concept, too! Check out their FAQ.

i've always said that i'd be fine with eating meat, so long as

1. i could grow it in a vat, and
2. it was seeded with cells taken from myself (as opposed to another animal who might rather do other things with their biomass)

Maybe one day i can eat meat again...
