This code works, but please note that it is provided as is.
It had only been tested in a localhost development.
There's a function extracted from the plugin Multisite User Management, which is based on the get_blog_list function, that has been deprecated.
No alternative available. For performance reasons this function is not recommended.
The user meta has to be checked individually, i.e.: Aim, Jabber, etc.
