WIll be interesting to see how the multi-site capabilities will be included in the admin interface.

Imo, keeping these functions quite hidden per default could be a good idea for the gui to not make it too cluttered for the majority of WP users who will not be interested in the multi-site capabilities. E.g. activating all these functions with radiobuttons with "Activate multi-site capabilities? Yes/No" from Settings --> General with "no" per default could be a start? Or are there advantages from WPMU that standalone WP could benefit from that I miss?

Anyone have a clue about thinking in this area?
