Interesting point. But the dcom client would be windows-specific? (those I mentioned - the perl mondules, openoffice, run on windows, as well as unix boxes - not sure about gnumeric :-). In fact there is a very perverse way of doing it - ActiveState provides a PerlCom product for hooking up dcom with activestate perl. i.e. you can go via R -> RDComClient -> PerlCom -> ActiveState Perl -> SpreadSheet::* . Just so that it does not require Excel installed or an MS Office license... In that sense, probably technology based on bridging over odbc is also acceptable?
