Whoa! Be careful there, there is no collective "you"; this is a
mailing list. 

S?ren, Dirk, Gabor, and I are four quite distinct people, and at least
Dirk and I are Linux people who would rather not touch COM...
Especially not when there's a perfectly fine library embedding method
available. This approach usually works across all platforms although
Windows and Macs tend to require a few extra twists. (I'm not up to
speed on Macs. I gather that OS X managed to mess up dynamic linking
somewhat but I believe it has all been sorted. You should probably
have a peek at the MacOSX FAQ at
http://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html and the page
http://www.economia.unimi.it/R)

...and Stefano and Simon who were the main players in this development
are yet another different "you".

Sounds good. I wish I had more time for this, but there's a deadline
approaching...
