I'm thinking not, but is it possible to pull up changes others are currently working on? I know they can shelve, but just thinking if someone (with proper security) could actually access a read only copy of their pending changes w/o them having to shelve that would be a super cool and useful feature.
"Pending changes" only exist on an individual's machine, so no, you can't see other peoples' changes unless they somehow put them on the server, either in the form of a check-in or in the form of a shelveset.
