In the interest of avoiding duplication and speeding up the calculation, I'd put this into the vignette() function (e.g. add an attached=FALSE argument). I suspect on a system with several hundred installed packages vignette(attached=TRUE) could be quite a bit faster than searching all packages and subsetting afterwards.

Both of these things would be really nice, but I wouldn't hold off on Seth's suggestion to wait for them.
