neat stuff.

i took a quick look at pricing -- $0.15/gb/month plus $0.10/gb to transfer
data in.  assuming it's the data motel and it never checks out,
500GB would cost $1500 to store for a year.  but 1GB would cost
just $3.  this seems nice -- my fs has only 2.5GB of stuff.  and even
at my cost of $100 for the recycled machine, that $1.60/gb/month.
but i would need to cache all that locally & have a duplicate copy.
so what usage senerio do you have in mind for venti/s3?

skip: what are the principles of operation of s3fs?  what's the advantage
over venti?
