Thanks everyone, the NP$ really weren't necessary, but thanks, it's nice to be appreciated

I actually started doing something similar to domaining.com, before I found out they'd already done it. and better. ( that's the story of all my web development projects )

Anyway, if you want an example of using magpie rss, there's one here:
http://www.namecodex.com/

And the source:
http://www.namecodex.com/rssaggregator.zip

I suspect that what domaining.com is doing is pulling down the rss feeds into a db using a cron job, and then sorting by date. my simple example is just live feeds, cached for 24 hrs, and ordered by blog, not most recent.
