Thanks francesco1119, good information. I'm a bit scared of that WP-i18n you mention, as it doesn't look like much is going on with it. I'm not opposed to paying for WPML (or, rather I doubt my client is... and they probably even qualify for the free non-profit version) but it looked like a good bit of work to get going and maintain, and overkill for what they need, other than SEO compatibility. They really just need to provide an alternate language version of some of their blog posts.
qTranslate just looked so simple in comparison, and a good fit. But, if it is problematic, than we wouldn't want to go that route either. I was really just hoping for some feedback from Joost, aside from... we won't support it.
I do like the idea of a separate page for each language for everything, if it isn't too hard to get going and maintain. How was your experience in that regard? Maybe I need to take another look. (I seem to recall that it looked like a good bit of coding work to implement back when I checked... and administrative work to maintain the linkage between all the versions of the same article/page.)
