Here's a scary idea.. A plugin that can aggregate feeds from other
locations. Presumably there would need to be a cron job to build the wiki
periodically, and each time it's built any new items would be turned into
pages etc. There might also need to be a way to expire old items, unless
you wanted to keep them forever.
This would allow ikiwiki to work as a kind of a planet, or at least a
poor-man's news aggregator.

XML::Feed has a very nice interface, may require valid feeds though.
How to store GUIDs? Maybe as meta tags on pages, although that would need
caching of such metadata somewhere.
How to configure which feeds to pull, how often, and where to put the
pulled entries? One way would be command line/config file, but I think
better would be to use preprocessor directives in a wiki page, probably
the same page that inlines all the pages together.
Where to store when a feed was last pulled?

So I need:

A way to store info from the preprocessor directives about what pages
to pull and expiry.
A way to store info on last pull time, guids, etc.
Switch for a mode that a) pulls b) expires old c) rebuilds wiki (for cron)
