So the ethical dilemma of 'killing' more viable embryos Bush was 
addressing when he made the ban isn't even the issue here.

He's just making more embryos to be 'killed', which doesn't matter in 
regards to debate going on in the US because the US ban on federal 
funding using new 'lines' doesn't apply to the rest of the world which 
is free to keep developing new lines.

I'm not sure I understand the significance of his research... was this a 
better and faster method to produce larger quantities of the same 'line' 
than current methods available?

I'm understanding from your last post quoting Bush, that the different 
'lines' are genetically dissimilar (that's what I was confused on), 
which answers my most recent post full of questions.

So... am I correct in things are like this.

Old way of doing things.
1. Extract stem cells from 1 embryo to create new 'line'.
2. Start using cloning methods to duplicate the stem cells in that line.

and the New way of doing things (The Korean guy's)
1. Get an Embryo.
2. Duplicate it a bunch of times to create thousands of identical 
embryos which would all be part of the same 'line'.
3. Extract the stem cells from thousands instead of one embryo

So...  is it that the method of propagating the 'line' is different?... 
in one method, one embryo (if it is a life) is killed and arduous and 
expensive and time consuming methods are used to duplicate its stem 
cells, and in the other method thousands of embryos are killed and their 
stem cells extracted in a much faster and less expensive and arduous 
method to get the same number cells that would have been gotten with 
method one.

Sorry for my ignorance.  I had understood the issue to be the techniques 
of the _use_ of the stem cells, and not the techniques of the production 
of the stem cells themselves.

Are my explanations of what I think you seem to be saying correct?
