More so the developer split, that and a couple of outstanding technical
issues.  Pretty much deltup is developmentally dead, and the patch
repository that it used is quite out of date.
As it stands, deltup I'd like to get out of the tree as soon as
possible- I've already added a warning to the existing ebuild to this
effect.

Well, it's a double edged sword- it reduces bandwidth usage (if the user
isn't wiping their DISTDIR often), but it increases the mirror size- the
latter seems to be one of the stickier points of getting patching
support implemented.

Deltup's only tweaks to portage was the addition of dtu.list.aux (if I
recall the filename correctly) to profiles/, and setting FETCHCOMMAND to
call deltup prior to the normal fetchcommand- akin to how distcc/ccache
are called w/ the normal gcc command passed as an arguement.
