Skyrim - Mods on Console Versions?

I haven't made it through the avalanche of Skyrim previews from the other day so this might already be out there but Next Gen is highlighting comments from Todd Howard about mod content on consoles. To be absolutely clear, Todd says there are barriers and it isn't likely at release but the console versions are compatible with mods - if XBL and PSN would distribute them. He also specifies consoles are "90% of our audience", for those interested in such things:

“It works on all the consoles,” he said. “As far as the 360 and PS3, right now there’s not an avenue for us to make that available, but we’d very much like to find a way. We have talked to Microsoft and Sony, and so there's a chance it might happen one day, [but] I don't see it happening for release.

“We'd like to see it happen, because it works, it's how we made the game. I think it's something really cool about what we do, but 90 per cent of our audience is on the consoles, so 90 per cent of our audience can't even see this thing. So if we can solve that we'd like to.”
