Try Special:Piggyback
is this extension when installed visible in [[Special:Version]] ? are there any open wikis you know of that use it?
It does show in Special:Version. There's also a private log (viewable by the same people that can use the extension) on the wiki showing who logged in as who. It's used on Wikia to track down bugs. For example, if someone says they can't edit, you can log in as them and work out why.
