Adding it to shared tables like that sounds a bit too much like a hack.
I wrote some of that tableName code myself, the quoting trick should work
fine.
'foo' will be treated as a local table name and have prefixes and shared
table stuff applied to it.
A quoted name like '`foo`' will be left alone (to do this in a database
independent way use $db->addIdentifierQuotes( 'foo' ) and it'll work.
Names with a database name applied to them such as 'bar.foo' should end up
something like '`bar`.`foo`' with no prefix applied.
Though really, if this is for the local wiki and you're writing an
extension to incorporate that into the wiki, and you're already thinking
of using prefixes. Then I'd just mandate that table names should be
something like {$wgDBprefix}somename_{thetablename} where 'somename' is
some short version of the name of the other system you're incorporating
the database from.
Either that or use a separate database name for the other data.
