Comment:

 attachment:31127.diff is a work in progress, feedback welcome :)

 It's backwards compatible with the current format of the signups `meta`
 column. Instead of making this field an array, it adds an array element
 named `other_blogs` where, if a user is signed up for more than one site,
 the other site signup info is stored.

 Some modifications to `wpmu_validate_user_signup()` were added, to ignore
 user_name and user_email collisions if the signup is for a site different
 than `current_blog`.
