The bleeding edge first pass bits are here-

I've successfully tested something that either is equivalent to that build, or very very close. But I'll put out a really tested srpm in a couple more days, which hopefully will also have the useful separate-filesystem persistenthome feature, as well as the global persistence incorporated here.
I will take a look at this updated version of livecd-tools. To incorporate this version into the current livecd-tools project, I will explode your source RPM, examine and pick the relevant patches.
The patches themselves were all just vanilla downloads from the gitweb 'raw' links. I believe I only put relevant patches in. Or rather, I think I took all the patches up to the mayflower split because I knew they would apply, then after that only took relevant, or what seemed like really useful patches.
[...] LiveUSB persistence [could] be much more usable. I.e. currently your overlay file resources can and do get drained by created and deleted files that the block layer at the moment doesn't handle as efficiently as possible. This is also the reason why you might want /home on a seperately mounted, not-dm-shapshotted loopback file ala the persistenthome feature.
I updated the livecd-tools package from version 014-5 to 014-7. This update introduces new interesting features: - adding the persistence feature (persistent overlay) - thanks to Douglas McClendon - fixing /usr/bin/livecd-iso-to-pxeboot script: was broken in the previous versions of livecd-tools 014 - creating a minimal /dev instead of bind mounting the host's /dev
You will need to recreate a LiveCD ISO image with livecd-tools 014-7 in order to use the new '--overlay-size-mb' switch of the livecd-iso-to-disk utility. If you use an older LiveCD ISO image, the overlay will be ignored.
See https://projects.centos.org/trac/livecd/wiki/ImageFlash for instructions about creating a LiveUSB media with a persistent overlay.
