I haven't really had reason to delve into aolserver cross-thread caching (or copying) as yet, so I'm not familiar with the techniques to do so.
Is there a way to make the objects available across pages and threads? I see that it would be a fairly straightforward fix in this instance to just re-parse the install.xml file again in the referencing page. But how about in an instance where we really do need them to persist?
