Currently outside tools such as <http://toolserver.org/~luxo/contributions/contributions.php> are used to retrieve the equivalent of [[Special:Contributions]] for a particular IP or username across Wikimedia wikis. It should be possible to implement such functionality in an extension (similar to GlobalUsage for files). A user would be able to visit Special:Global Contributions (or some equivalent), input a username or IP, and retrieve the equivalent of [[Special:Contributions]], but in an aggregate form (on every wiki where the user or IP has been active). Filing this is as a new extension request.
*shameless plug* See also http://toolserver.org/~krinkle/MoreContributions/ which does something similar but in chronological order instead of per-wiki (also supports wildcards). Often used for ranges. Can be used as a range-contributions for one wiki and/or a specific user on all wikis.
