If you keep your /etc/passwd and /etc/groups in sync, you should not have issues between the two /home's. (Then again, conflicts between multiple versions of gnome or kde, etc, could be an issue - how about a "shared" space, and make /home just a gig each) 2) It is possible that each distro will trample over "its" /boot, so it would probably be best to use separate /boot paritionsn, plus grub. What difference does 50MB make, anyway? 3) Consider LVM.
