Hi Claudio, I think the best software for a community is OpenACS, because it was conceived from the begining to build communities, purpouseful communities! I will give you a couple of links that I'm shure that will help you, please read the Etzioni article about CMC, it will help you a lot, most of the requirements are met by openacs 4.5, also check out the Study cases that aD has and the ASJ, maybe you will find interesting things in wimpy point at aD too.

And if you can find more info about AIESEC.net that aD did, it will help you a lot, maybe Malte know more about this?, if not, ask me again because the IT directory at AIESEC at that time is my friend here in
Guatemala.
This stuff has helped me a lot in sales things... =)
And about the java, it doesn't make sense if you want rapid development, and about the MS stuff, you know, there is a lot of docs out there against them and their technology. I think your best point to convince is to show the community stuff that no system else has.
