I get the distributed disk structure thing. I'm using that already locally, but
my network pipes can't cope with maximum rates :)

But if it's serving 1000 different 'sites' in parallel ? My own sites are all
cached across machines and are all generally in memory on the machines they are
running from so no disk traffic is needed? I can't imagine that all of the sites
will be 'live' on the cloud, so need to be loaded every time they are accessed?
Surely the trade-off is between time it takes to reload an application and data
to a location that can run it against simply accessing a real machine that has
it available locally?
