Implementing this for using "string" and "char *" alternatively would
be no problem with our IDL compiler, however I do not think this is
in any way a good idea.

Implementing the multi-signature approach is IMHO even less a good idea,
because
a) in the skeleton, bar(char *) cannot be implemented without
stubbing bar(string) --> no real compatibility.
b) imagine the following IDL: 
"baz(string,string,string,string,string,string)".
would you want 64 methods for implementing every conceivable
combination? *BLOAT*

Please think about just sticking with char *'s. Standards exist
for a reason, and in this particular case, the code overhead
on your side is really minimal.
