The only tool that I know of which is even close is GCG's FRAMEALIGN. It
aligns a protein to DNA, allowing for frameshifts.  It is the only safe way
to go when aligning to an EST, since they have a very, very high rate of
frameshifts and other errors.  However, it assumes that the protein
sequence in the comparison is fully in the correct frame, which might not
be true if, for instance, all you had to start with is a collection of
