That's an interesting idea. On the Zope side, you'd just have to set
up your templates to spit out html containing SSI directives, obviously
no problem.
But what's involved in the Apache configuration?
Is it easy to set up SSI processing of content delivered via
mod_proxy or mod_rewrite?

Not sure I follow this. What does the final assembly?  Your main ZPT
template?  If so, why not just cache the xhtml-fragment portlets in a
RAMCacheManager instead? Probably faster than waiting on network traffic
to/from squid, and definitely easier to set up.

Another thing I've thought of: Put your portlets in iframes.
But I've done only minimal work with iframes and don't really know what
the implications are.
