Ooops.. turns out the full gh-pages checkout is now a whopping 1.6 GB..
Checkout data transfer was less then 100 MB.. but when I check-out gh-pages my PC was not happy. Github probably not so happy too.
With sharing of assets and some minification etc it'lll probably be a little less but if we pursue this a real CDN would be good idea.
Also at some point I'll ditch this repo and restart to cut-down .git size.
