Hi Ludo,
I have mentioned your work on #launchpad at 
irc.freenode.net and the
launchpad team is interested in helping out.  I have an "appointment"
to talk to danilos in about 2h so if you or Vincent are interested
maybe that would be a good opportunity to learn more.  I will report
back otherwise.
Some of the things you may want to think about:
- There is actually already an xwiki project in launchpad that I
created a long while back, danilos suggested that translation should
go through there
https://edge.launchpad.net/xwiki
- There is a way to group projects together in launchpad which would
take care of translations for the different components, applications
etc
- There is an api initiative, currently in beta, which could provide
an elegant way of meeting all of your requirements through mixing a
launchpad backend with a  lightweight xwiki app.  The api could help
out in automating SVN sync although it currently doesn't focus on
translation features but maybe its not too hard to put some features
like that on the roadmap.

To my knowledge launchpad is going to be released as open source, but
is not there yet.

 Hi team,
 I wrore a report about the different localization strategies we could have
 for XWiki comparing:
 - a simple tool Jean-Vincent wrote
 - an L10N app I started to build
 - using 
launchpad.net
 http://dev.xwiki.org/xwiki/bin/view/Drafts/Selecting+a+tool+for+managing+Lo…
 Please review and add requirements if you see requirements that have not
 been listed. I think we need to look at the applications and evaluate them
 in more details, especially to see of 
launchpad.net could work for us.
 Let's discuss.
 Ludovic
