You can create as much A records as you want and you'll receive round-robin configuration. To give more exact answer I should ask you: what you are looking for? just load balancing and/or high availability? Also I think that Squid is not very good solution as minimum from your customer's point of view. We are using our own, DNS-based solution and we are happy with it.
