Given that the code has already been migrated over to launchpad and is using bzr, I just want to ask, do you really want to introduce a different dvcs for everyone? It's understandable if you have much better experiences with git vs bzr given the comment about dealing with revision control problems. I'm not voting since my commits are minimal and generally things like fixing builds on newer compilers.
As a side note, I've been thinking about moving the inkscape mailing lists over to launchpad as a post-release todo item to get Inkscape moved more away from sf.net
Regarding distribution of releases, does anyone know if LP tracks stats and makes nice graphs or charts and could import that information from sf.net
(relating to download information)?
