At least I have missed environments at some point. I think that Franz has put the most work in this direction, see http://www.franz.com/support/documentation/current/doc/environments.htm#envir-general-1 And if I remember posts by Duane Rettig on comp.lang.lisp right, they would be quite willing to cooperate on this issue with other implementors.
