Debate on Embryo Adoption

From the May 30 Washington Post:

Some Catholic theologians are encouraging married couples to adopt unwanted embryos from fertility clinics. Others vehemently oppose the idea, calling it a grave violation of the principle that procreation should occur naturally.

The Vatican has not yet taken a stand. But if Pope Benedict XVI rules against embryo adoption, as some doctrinal conservatives expect, it could create a fissure between Catholics and evangelical Protestants, who have enthusiastically promoted embryo adoption and enlisted the White House's support for it.

Any thoughts from co-bloggers or readers on whether embryo adoption would (as one theological critic puts it) "make Catholics complicit in test-tube fertilizations, which the church considers illicit"?  Or is it (as a theological supporter puts it) a justifiable act of "reaching out to another human being, albeit in an embryonic state, in the only way that that little being can be helped"?
