[Tilesathome] Distributed server idea

[OJW]

At SotM conference, various people discussed ideas for hosting tiles, much 
more innovative than the "single combined database/webserver" idea that we 
use at the moment.  

For example, most of the computing power we have is held by contributors 
rather than being in the OSM server rack.  It's not always available, and we 
don't necessarily trust every machine, and some machines have more facilities 
than others (disk, bandwidth) but we could design a system that works around 
those limitations.

I sketched an idea, and put notes at:

No software exists yet of course, but I seem to remember several people 
interested in server-side coding, maybe they would find a distributed project 
like this interesting to develop?
