Create an RSS feed of my spy block / latest activity list

I want to share details of the activity on my Boonex Dolphin site on another website I own (which isn't a Dolphin site).

I figure the easiest way to do this would be to use an RSS feed of the information shown in the spy block (Latest Activity) on my Boonex site. I could then pull info from the spy block RSS feed into my other site (which has a widget for displaying external RSS feeds). However although Dolphin automatically creates RSS feeds for a lot of the standard pages / elements, the spy block doesn't have one for some reason.

Therefore I'm looking for someone to create a module (or modify my site) so that it produces an RSS feed of the spy block latest activity.
