Depending on your language, you might be able to "fudge" this up to work for yourself. In C/C++ I have a function that automagically decides whether I am beginning a new transaction when I am calling it or whether I want Oracle-style nested transaction functionality. My rollback function is aware of this also.
The only thing that you can't do with this approach that Oracle can do with it's nested transaction functionality is (to my knowledge) alter the isolation level at each SAVEPOINT. For reasons unknown to me, Oracle allows this although I can not actually think of an application for it.
