I guess I'd approach it by tweaking your RSS feeds such that the PubDate is
the date the event occurs rather than the default of the date the entry was
entered into the system. Otherwise, you have to add some sort of
non-standard tag (in the description maybe?) and build a system that sorts
on that.

I would have suggested Yahoo Pipes to do the merging and sorting... I'm
disappointed to hear of its pending demise; it was a powerful tool. Thanks
Conal for the link to the alternative services.

Once upon a time, I created a Pipe that merged a bunch of RSS feeds from
Scopus listing new publications written by a set of faculty members (one
Scopus feed per individual) to create a combined new publication list for
their department. Pipes also made it possible to proxy the URLs in the feed
and allowed the creation of email alerts (where the proxied URLs were
crucial for off-campus access).
