Well, something larger than several tens of megabytes.
(To be a bit more precise, we should differenciate betweeen "plain"
embedded and small devices ;-p)

I'm more speaking of much more finer granulated build configuration
(esp. feature switching). That's more an issue of invidual ebuilds
and profiles than portage+crossdev.

Some things that seem to be completely missing:

* multiple different targets with equal targettype-tuple at the same time
* minimal sysroots on per-package build (so only dependencies of the
  individual package are installed in the sysroot)
* parallel builds (w/ different sysroots instances)
* easy integration of custom postinstall filters/checks
* custom source branches/patches (w/o touching individual ebuilds)
