FWIW, from the top of my head, we have at least:

 - SwClient/SwNotify
 - tools/link.hxx
 - SfxBroadcaster/SfxListener

and a bazillion other implementations that I forgot about of the observer
pattern in LibreOffice. I would much prefer _not_ to introduce yet another
implementation, but rather use the least broken of our own.

And if something like boost::signal2 is awesome beyond believe (which is --
given Michaels hint about LOCs added at least open to debate), we should first
make our least broken implementation wrap or subclass that as a migration path.

Best,
