Transplanting a uterus?

A story I just couldn't miss... Successful uterus transplant in ewe - Scientists have successfully transplanted a uterus in a sheep. The hope is that such a transplant will be available for women in about 5 years. There are some major problems - the transplant would have to be from a relative (mother, sister) and could only be in place for a maximum of one birth or two years (whichever comes first).
