Those data were from r-base, and I thought that following our discussion 
on licensing, it would have been better not to use them.

The think I really like with the datasets in R is that any package can 
depend on them for demos/examples/etc... I don't know much about 
easy_install yet, but does the dependency tracking system work well ? 
For example, you install foo which uses faithful in some examples, when 
is the dependency resolved ? Would it be ok to use them in tests ?

For the old faithful data, the answer I received from Pr Azzalani (whose 
article "A look at some data on the old faithful geyser" has original 
data) is that an acknowledgment would be welcomed, so if we acknowledge 
it in the sources, is it OK to apply BSD (the problem would be if people 
using it would be required to acknowledge as well, right ?)
