Actually there's something in Rubygems that will load a bundle
even if you require .so - I think it'll also load a DLL on windows
if you ask for an so... just to make life easier.

I don't think so. Quite a few gems require *.so, and work cross- 
Look at RMagick for example.

Yes, did that yesterday, he doesn't answer the questions I asked.

I was... not now. It's what I did in the past with the one-wire gem too,
especially since Windows users often don't have a C compiler. I still
haven't learnt how to do that properly, but for now, it's not needed.
