a.sl.o handles the syncing. Before the bundle is marked public, via
the editor panel, it is stored locally. After being marked public, it
is automatically pushed to the download server. All syncing and
redirecting is handled by Remora.
The big win is that by moving the files off the primary server it
reduces cache churn on the primary servers and db servers.

+1, Whenever you get a chance wes and I can start work on this.
possible work flow:
1. Bernie (or vm maintainer) creates new vms.
2. Bernie (or dns maintainer) points dns names at new vms.
3. Wes (or aslo admin) sets up stock also server - I can help point
wes to the necessary http configs and create db backups.
4. Wes (or aslo admin) syncs aslo instances against correct git branch
- will appreciate alsroots help here.
repeat 1-4 with activites-testing.sl.o and activites-testing-dl sl.o
repeat 1-4 with activites-dl.sl.o -- and go live
