Uhm, this is a pretty weird statement if you stop to think about it :-)

There is no way you could serve a dynamic file from an accellerator
without defining it as 'static' for a minimum short period.

The advantage to running varnish in front of static content is that
you can avoid loading of your disk system, and, as far as I can
tell, concentrate your investment in the bits of hardware you get
most benefit from: RAM instead of CPU.

Finally, I would advice you guys to seriously look at flash-"disk"
drives.  The virtual elimination of seektime is just what you want
from a web server or cache.

I have had the Mtron PRO7000 series recommended, and will be getting
one RSN to play with, I'll let you know what I find.

Never attribute to malice what can adequately be explained by incompetence.
