The only thing I can think of is GCG's backtranslate which will give
you the most and least probable DNA sequence.

On a similar note and while I'm thinking of it does anyone out there
know of something that will compare 2 protein sequences at the DNA
level and give you the most likely DNA alignment.  I'd find this
useful for finding possible undetected frame shift errors in multiple
alignments.

Thinking about it this is trickier than I first imagined and not just 
a quick perl hack.
