I could agree more with this statement.  Please consider doing this.  I wanted 
to do this about a year ago but could not find enough help/support to do it 
(it'd be a major job).

I can give you tips on how to do it and even get you started off - I have a 
sense of the type of code it'd require, but it'd take time to create all the 
conversion rules in Scheme.
