I'm sure it would be technically feasible for a program to either be
aware of PAE directly, or to request swappable pages through a
transparent API, so that the program could work with more than the 3GB
limit. I don't, however, know of any such implementation, and generally
it's easier to just move to a 64-bit OS ;)
