blag - le brixton linux action group
works to overthrow corporate control of information and technology through community action and spreading Free Software.
I'm not sure how many governments would want to work directly with blag after reading that. ;)
In general, I think blag is better on the desktop and with more cutting-edge servers like asterisk than it is for things like apache. For apache I think debian is a bit better. That said, sites as huge as wikipedia use fedora's apache which is basically the same as blag's (or vice-versa).
You may want to check out linex as well to see how well it fits what you are looking for. I haven't used it before.
It does seem inevitable that countries in South America will start using GNU/Linux more & more as time goes on. There's big commitments in Brasil and Argentina and probably others so far.
Feel free to ask any questions about your project here, and keep us posted. :)
Oh, and the blag star/button thing that is on distrowatch is basically our "logo" which you are free to use. :)
