Having previously added CoolIris support to my RedBubble wrapper site I decided to go ahead and add it to my main photography site. Because of the way things work over there it took a little more effort but, now, I've got it working:
For those interested in the technical details: I obviously didn't want to create one honking great RSS feed of every photograph on my site, that'd be far too much data moving around all in one go. Thankfully the advanced developer documentation (note: no direct link to the documentation in question — fancy JS tricks are fun for some things but for documentation? Meh!) points out that a feed file can have next and previous links so I could create a feed for each individual album and they could all point to the previous or next albums.
The nice thing about this is when you're viewing an album and you hit the CoolIris button in your toolbar you're taken to the part of the wall that's displaying those images. Then, as you move about, the wall grows in the direction you're moving in, following those previous and next links.
I'm now toying with the idea of adding a MediaRSS feed generator tool to RBArtMan. Extra (X)HTML hacking would be needed to make it all work on people's own sites but it would mean that most of the grunt work would be done for them. I'm not making any promises, it's all down to available time.
