anyone used Varnish yet?

hi everyone,
 I just read http://www.catalystframework.org/calendar/2008/14

 I have seen some mentions on
http://www.mail-archive.com/catalyst@.../msg04620.html
and http://www.mail-archive.com/catalyst@.../msg06552.html .


Was wondering if anyone's used it and have any words of praise/complaints?

thanks
k. akimoto
