Varnish use for purely binary files

[pub crawler]

This is an inquiry for the Varnish community.

Wondering how many folks are using Varnish purely for binary storage
and caching (graphic files, archives, audio files, video files, etc.)?

Interested specifically in large Varnish installations with either
high number of files or where files are large in size.

Can anyone out there using Varnish for such care to say they are?

Thanks!
