Would be nice if offloading (perhaps by means of squid proxys) would be possible. We could make a proxy packege for people to install which they can use to help reduce/spread load.

Serving tiles is unlikely to an expensive process. OS will cache filesystem reads regardless. It would be better to optimise HTTP headers to improve caching (and hence offloading the server) and also support Conditional "304 Not Modified" HTTP Requests.
