Sorry, no, I should have been clearer about the context. Siamese twins
are often separated by a medical operation (whether this is ethical or
not we will leave aside, often this is done for medical reasons).
Depending on the degree of twinning this may or may not be done
in an "equitable" fashion. Usually doctors or parents must "allocate"
body parts to one "brain" or the other. When I speak about cloning,
I'm refering to "brainless" body cloning to supply a complete body for
one of the twins.
The word "clone" is overloaded at this time since we can have both
"inhabited" and "uninhabited" kinds. We need distinguising vocabularies.
[The medical term is something like aencephlic, but I can never remember
it exactly.]

Again, we are in the swamp. My usual use of the word "clone" refers
to the brainless variant. I see relatively little use for identical
twins of different ages, though one could presumably argue this could
be benificial to society for instances like Einstein.

True, but so are computers, TVs, VCRs, running water, toilets, etc.
You can't easily invoke "historical standards" in a moral discussion because
you are on a very slippery slope.

We all do this already with our own parents and older siblings. They all
share some of our genes and all serve as role models for us. Twin studies
show that the interesting stuff (intelligence, longevity, etc.) is only
about 50% "genetic" and so as long as these facts are emphasized I
think the risks would be minimal.

Agreed. But we can't tell when we create *any* child whether it
will turn out good, bad or unpleasant in advance!

One would presume that you would only activate a "clone" if
the first one turned out "well". Presumably this implies that
(a) the original copy had "good" genes (something we will be
able to test for in the not too distant future), and (b) the
parent(s) were able to afford the rather expensive technologies
required to produce clones. So the individual will likely grow
up in a fairly priveleged environment.
I'm assuing here that *most* clones will be of the form of
split embryo's (e.g. twins of different ages). If you are
refering to the "lets make a clone of Robert" scenario
(I'm flattered, really I am...) -- What possible reason is there
to do this? (other than shear egoism or the Einstein scenario.)
I think this is what everyone is afraid of and I can't make a reasonable
argument for it. If we have the technologies (reliable & inexpensive)
to make copies of ourselves, why would you do that? Why make a copy of
a program that is fundamentally flawed? Remember nature is working
blindfolded with its hands tied behind its back. It looks like designer
children and cloning technologies are going to race neck and neck in terms
of reliability and costs. I would say that designer children
trump cloning in the minds of what most adults would want
for their offspring (and as I've argued this is questionable
from the ethical standpoint).
>From a risk standpoint, I suspect designer children are more likely
to have unforseen risks than a simple cloning exercise. There are
big problems to be overcome in both areas and even with the genome
in hand those problems might not be overcome before hard nanotech
hits (so they may cause a lot of noisy discussion but be generally
irrelevant).

Yep, but "on balance", given the probable wealth and intelligence
of the people most likely to use these technologies in the near future,
I would say you would have a better case arguing that "emotional problems"
would be more likely to occur in children born to families living
below the poverty line or to parents who have low IQs. Is it ethically
wrong for these people to have children?
[Please no flames... I'm not making claims but am posing arguments
based on observed statistics.]
