It would not be the official copy, of course, that would remain in your Savannah repo (http://git.savannah.gnu.org/gitweb/?p=gnash.git;a=tree;f=po); but it would be a convenince to our substantial localization group (over 1800 localizers working on over 100 languages/dialects) and could be used by your folks as an improved collaboration platform for L10n.
I've noticed that Gnash has relatively few languages (<10) and fairly low completion levels. I believe we can improve on that if we host a copy of your PO files on our Pootle server. This is important to us as a downstream that ships Gnash as part of our builds. I anticipate more L10n activity to come from hosting it on our Pootle server than by simply pointing people to work on your unhosted L10n (mailing list) workflow; however, we would not look to have the same repo commit linking that we establish for projects in our git repo. There would still be a manual process of upstream submission and commit after the PO was finalized. Our Pootle server would merely serve as a collaborative tool for finding and completing the PO.
I believe that some of you are fairly familiar with Sugar Labs / OLPC and that there are a number of Gnash project members that are also Sugar Labs / OLPC participants (John Gilmore <jgilmore>; Tomeu Vizoso <tomeu>; Sridhar Dhanapalan <yama>). You hopefully know that Sugar Labs (especially the L10n community) tries to play well with others. What I am proposing is essentially a matter of enlightened self-interest, which I could have done asking without permission, but I wanted to see how you guys felt about this idea before proceeding.
