I would suspect that we can make it use overlayfs using the same infrastructure--it'll just need teaching about the new filesystem type.
Hasn't overlayfs support been in schroot since 1.5.2-1 (May 2012)? I don't think any more support is needed on the sbuild side. Ubuntu seems to be making active use of overlayfs chroots -- mk-sbuild from ubuntu-dev-tools 0.136 (November 2011) onwards makes them, and they carry no patches to schroot and no relevant patches to sbuild.
All you need a kernel with overlayfs support. Ubuntu's been carrying the patchset out of tree for a while.
(I was pretty sure I'd _used_ overlayfs chroots, so I was surprised by the implication that it doesn't work yet...)
By the way, regarding cowdancer and LD_PRELOAD, I semi-recently learned about fakeroot-ng, which implements fakeroot using ptrace instead of LD_PRELOAD and is therefore more reliable. I wonder if the same approach could be applied to cowdancer. (I've long wanted a "fakeschroot" that doesn't require elevated privilege in order to build things....)
