I think that it could be a minor burden, but usually it should not be 
too much of a big problem. If the old code is written in Pascal or 
Delphi there is the Apollo bridge (though I'm not sure how active that 
project is nowadays, see http://www.moriq.com/apollo/index-en.html) and 
even if that fails to meet the requirements it should not be too hard to 
bridge your code to C and to Ruby from there. .NET might be a help there 
as it bridges lots of different languages (Ada, Fortran, Basic etc.) in 
case you are on Windows -- I'm not sure about how many languages Mono 
already supports.

I'm not an expert at this area, but tasks like these seem to be possible 
in the general case.
