Hi all,
Mosquino now has a Google Code repository. Boards for the rev2 (incl. some power and I/O shields) are finished and going onto a batch order tomorrow 
I'll wrap these up into official 'downloads' once I build one and see that it works, but until then you can download the files using a Mercurial client or the Source tab. EAGLE files and gerbers are in the 'hardware' repository (click the 'Repository' dropdown list).
Newly added: 0.6V micropower boost converter power shield and LiPol battery stackable power shield.
I'll give another update when these boards arrive!
