You can use a very thin front-end Apache reverse proxy or load balancer that forwards the requests to one or more back-end Apache servers that use mod_perl.

You can set the front-end server to forward the requests to some paths to a comet server.

This solution is scalable if the trafic increases.

Read more about the Apache modules mod_proxy and mod_proxy_balancer.
