BBC is reporting an Iranian offer to have France set up nuclear processing plants on Iranian soil and both control and monitor the operation:

Iran has suggested that France monitor its nuclear programme, by setting up a nuclear fuel consortium inside Iran. ... The deputy director of Iran's atomic energy agency, Mohammad Saeedi, told French radio that a solution to the nuclear issue could be a consortium with France to enrich uranium in Iran. "That way France... could control in a tangible way our enrichment activities," Mohammad Saeedi, deputy chief of Iran's Atomic Energy Organization, told France-Info radio.

Sounds like a good solution to me. Of course, there are many others, too. There's nothing especially urgent about the Iranian nuke issue that makes it rise to the level of a crisis.
