Seems like a non-issue to me, and the thought of creating human embryos only to harvest the cells freaks me out. Ever read Brave New World?
I know what you mean, Carlito. Although I wholeheartedly support stem-cell research for medical use, I have this vision in the back of my mind of walking into a barn one day and finding it filled 95 human arms in tanks.
Ok, let's clean up some misperceptions here.
Sitting in cold storage, waiting for possible implantation OR destruction, are literally thousands and thousands of embryos. When a couple goes in to get assistance with conceiving, the doctor harvests as many eggs as possible (figure up to a dozen), fertilizes as many as possible using the guy's semen, and then inserts a set of them (figure a half-dozen) into the uterus and waits to see if any of those "take". The woman beforehand makes a decision how many of those that "take" she wants to keep (just because if the whole lot somehow takes hold, all of them would be at higher risk of problems) and the doctor works with the proud parents (of a growing set of embryos) to cull the weakest of the litter. Can't think right now of a better way to put it, sorry.
Anyway, remember the remaining embryos that were fertilized? Well, if the first set doesn't take, the doctor doesn't have to harvest more, they just take from the batch already processed. But if the first set DOES take, those embryos sit in cold storage until the parents decide what to do with them.
Most people wait until they no longer want more kids (ever have twins or triplets? It makes you NOT want more

) and then they tell the doctor or the lab to go ahead and destroy those frozen embryos.
So why can't those embryos instead be used for federally funded stem-cell research? If you have a choice between the embryos being destroyed (you can't force anyone to keep them in storage forever or to get pregnant with them, sorry) or using them for research to cure some nasty diseases, which seems like the most "moral" choice? I know which choice seems the most "logical".
Next misperception I've read: that not federally funding stem-cell lines outside the ones that existed when Bush made his decision a few years back is somehow NOT slowing down progress.
Although the pharmaceutical firms do a HUGE amount of research, so do universities. And university research need and use lots of federal grants. Except in the case of using stem cells from "unapproved" sources. So it shuts down that option for research. And, by the way, who exactly controls most of those "approved" sources of stem cells?

I don't have the answer to that either, but I can certainly guess.
