What do you think about implementing a RSS as a tag in wiki?
It could work like this:
[rss from="http://someurl"|clips=10][/rss]
Above example could generate dynamically wiki's code inside rss tag like this:
- http://<clip_title>
Here goes the message...
- http://<clip_title>
Here goes the message...
- http://<clip_title>
Here goes the message...
etc.
