Just pointing out that 512MB or whatever is the new
requirement only applies to a fresh install.

Just pointing out that we haven't explored venti enough!
Other solutions are possible (with their own problems).

With the trick I am talking about, there is nothing to stop
you from connecting to N different remote ventis.  In effect
your local (by that I mean under your control, not necessarily
on the same machine) venti can be treated as just a buffer!

In spirit this is like much like what bittorrent does but much
more flexible.  Like in bittorrent you pull all the stuff you
depend on (but that can be done in background). You can even
start streaming your remotely stored video right away!
