In reply to arctic_hobo:
Decent boots with a good vibram sole climb as well and in some cases even better than rock shoes, specially on 'everything wet or small', with some obvious limitations such as slabs (due to the stiffness of the sole rather than the 'stickyness') and pockets. You just need to adjust your technique a bit.
I'm working on an idea for quite the opposite actually. A soft shell insulating shock with a light textured rubber sole that can be thrown over the rock shoes in easy pitches, belays and when hitting wet/snowed/icy/broken rock/grassy patches in Alpine routes, and they could double up as bivy booties.
Anyone having some spare dollars and wanting to invest...
