few months ago i wrote blueprint for importing wikipedia articles into plone. (reason was this post)
since then i didnt have enough resources (my leptop is not that fast) to import bigger set of articles into plone. i reached 25 000 articles then job was pushing and i need cpu for work. i would really like to see how far plone could go. is it possible to import whole wikipedia into plone? would be nice for promotion of plone... "look you can have wikipedia is that big enough for you sir" :P
well if you have some testing server that has spare cpu power and you are also wondering how far plone could go drop me an email and lets try too push it to the limits.
