Hi Pablo, Thanks for your comments. However I'm not able to reach a usable solution even with "nearest surface point". I've tried everything, without succeed. If you want to try I've uploaded a simplified version of the eye rig: http://www.pasteall.org/blend/14049 . The "target" bone should keep the eye looking at it. Then you can scale bones eyeball_internal and eyballe_external to change, independently, the size of the iris and the pupil.
Anyway, I think we both agree the "project" mode for the Shrinkwrap modifier is not working as expected and "using projection mode is not such a good idea, it has many many problems with rigged meshes. ". So I guess it should be fixed/improved/whatever. Is there a proper way to ask for this fix? I mean apart of a bug report or posting the problem in this mailing list ;) And about the complex deformations " but what if the face of the monkey was also deformed by other bones or shapekeys? ". I guess that is simply impossible to do right now. Maybe in a few years...
