Just stumbled on this again... three years later, the project does seem to be coming to life!

It seems to be somewhat like in alpha stage... has very basic stats page, no teams support, the client apps are very simplified too...

I'm running it here, and the client app (Grub Next Generation 0.9.3) does have some annoying bugs that I noticed. For example, for some reason here things seem to stall when grub is compressing/decompressing the WUs.
