Finally, I remind the package author about the original question:

- How to overload methods in classes created by R.oo package? [snip]

Maybe you missed it in the flurry of messages, but did the idea 
suggested by Gabor Grothendick not suit your needs?  I don't know the 
R.oo package, but Gabor's idea worked with the S3 class 
system, and just 

required some easily programmable syntactic processing to 
generate the 
method names.  (Basically the idea was that the generic 
function would 
dynamically create a class for its first argument, which consisted of 
the classes of all the arguments appended together.  If there 
is little 
inheritance structure, this should work fine.)
