The files are available if you know the exact URL, which is possible to 
figure out from the CVS module of the original SRPM and hash.

Right, this is not problematic at all to our own buildsys.  This might 
be a useful optimization for other cases.  For example, where plugins 
need the original source tarball to build.

This need not be inconvenient for manual builders and other automated 
rebuilds.  We only need an evil auto-downloader, but make it disabled by 
default.  Then manual or automated rebuilders can choose to enable evil 
by setting an environment variable $AUTO_GRAB_SOURCE if they want to 
automate it.  Otherwise it tells the user exactly what to do.

BuildRequires: auto-grab-source

%prep
%setup -q
GRAB_SOURCENAME=glibc-2.5-fedora-20061008T1257.tar.bz2
GRAB_HASH=6aa114e3cde495c267ff8a6e55b90bec
GRAB_NAME=glibc
auto-grab-source $GRAB_NAME $GRAB_SOURCENAME $GRAB_HASH

The pseudocode of this tool
===========================
if file exists and matches hash
   return 0
else
   if $AUTO_GRAB_SOURCE == true
      attempt to grab
      verify
   else
      display instructive error message about what to do
   fi
fi

Is this too evil and ugly?

Is this evilness worth avoiding 50MB+ of extra .src.rpm for all mirrors 
to throw around?

I don't have any opinion either way.  This does not effect our own 
buildsys, or anybody else building packages directly from CVS.
