I've got an RSS feed piping into the Enterprise 2.0 Room for items from Twitter and Del.icio.us. I'd love if the icons for these streams looked like Twitter and Del.icio.us, not the RSS/blog icon. When everything looks like that RSS icon, it seems to blend it all together into a big mass of orange.
I think it'd be a bit much to use a service's icon for something that isn't the exact service. On the other hand, rainbow-colouring the RSS icons to allow for easier differentiation would be nice. Given that FeedIcons.com provides 50 different colours, all that needs doing is adding the ability to set a particular colour for a particular feed.
