Right, that solution won't work for you then.

No technical reason.  In fact, some of the work has been done, I think.
If you want to try it out, there are some patches in this bug report:

http://bugzilla.gnome.org/show_bug.cgi?id=336174

Nobody ever got the patches to production quality, but it will at least
point you towards the relevant code.  If you or anyone wants to help
finish off this work, we could get this fixed in the 2.20 branch since
it does seem to be an often requested feature.
