I was thinking more in terms of what amzon would charge for using such
big images. [presumably charge rate would be higher]

The debug builds are huge. [perhaps they can be trimmed down a bit
with -g insted of '-g3' ]

Also we discussed defaulting to gcc-4.7+ - so I used fedora-18 which
has that default. And all the default developer software adds up to
the basic install.

I attempted a minimal linux with xfce [one of the light weight
desktops] If we distribute images we need a desktop - but with amazon
- I guess that could be cut down [and cut down X?] - and bring down
the disk requirement.

Also amazon images might cut down on swap and other stuff that might
take up space on a regular VM. [my cleaned up image of 5.4GB might be
with swap zeroed/compressed out..]
