Vegans and vegetarians, what is are your thoughts on vat grown meat?

If vat grown meat was commercially available, would it be acceptable for a vegan to eat it? This is assuming that you could get the genetic material the same way that the cops do, via a cheek swab, and that is a way that would not cause any harm to the animal. I'm sincerely curious as to what vegans/vegetarians think about the prospect of vat grown bacon.
