This would be easy for computational modules, and probably more difficult for
graphical modules. The problem is : what would be the benefit ?

ADE-4 and Splus are not intended for the same users. Splus is a professional
statistical software, very expensive and not very easy to use for biologists.
ADE-4 is free, dedicated to multivariate analysis and aimed at ecologists.
Ecologists will not buy $plus to use ADE-4, and professional statisticians
just need a single value decomposition function to do what they want in
multivariate analysis.

OK, this is a little caricatural, and it would not be so easy, as we would have
to deal with Splus objects structure.
