Recent  versions of varnish can use DNS servers for backends.  Even if 
you cannot use SRV records, you can always setup a separate DNS server 
with the "backend" addresses.  Some setups use a hack with load 
balancers where you can use the SAME IP address for the varnish and the 
"backend" server, making caching almost transparent.
