RSS for latest activity?

I'd like to get a run-down of the latest activity within our Dolphin site displayed on our main sitem similar to the 'latest activity' block we're currently using on our Dolphin home page. However the latest activity block doesn't have a RSS. Is there any way to create an RSS feed for the latest activity on our Dolphin site?

I know that there are some RSS feed aggregators out there but I am having two problems with these:

1: Not every section within Dolphin has an RSS feed (there is lots of activity shown in the latest activity block from areas that don't have thier own RSS) so the aggregated feed would be very limited.

2: Some of the RSS links that Dolphin generates aren't recognised by the aggregators. (For example the RSS feed for my sites module gets rejected for some reason: http://www.fieldstarnetwork.org/m/sites/browse/all?rss=1)

I can't really answer the others, but for no. 2, it's probably because you need to be logged in to view the feed.

... I think I need to make a ticket for that.

Thanks Nathan - I'm not familiar with how tickets work. Once this is fixed will to have to wait for the next version, or will there be a way to implement the fix before then?

In the mean time does anyone have any other suggestions on how to show / share community activity in another website?
