We have always been able to copy/kill/yank from one Emacs session to another,
even when the sessions run different Emacs versions. I cannot speak for OSX
10.6, but this has always been true on other platforms, AFAIK.

However, at least on Windows, this important feature has been broken recently by
some of the selection changes they've made in the development version (Emacs
24).  Hopefully this change is considered a bug that will soon be fixed, rather
than a "feature".  See for example bug #6689.
