Actually that should be quite easy to do with a shell script, using
inotify-tools [1] [2]:
- ---8<------------------------------------------------------------
#!/bin/sh
RPMDIRS=/usr/src/packages/RPMS/*
REPODIR=/usr/src/packages/RPMS
CACHEDIR=/usr/src/packages/RPMS/.cache

inotifywait -m -eclose $RPMDIRS | while read event; do
	createrepo -q --cachedir="$CACHEDIR" "$REPODIR" >/dev/null
done
- ---8<------------------------------------------------------------

Would just need to make it somewhat smarter and only run createrepo if
there hasn't been any write after a given amount of seconds (or
minutes), because if rpmbuild creates several RPMS, it will trigger
createrepo immediately although rpmbuild isn't finished with writing all
of them.

[1] http://inotify-tools.sourceforge.net/
[2] SUSE RPMs available in my repo:
http://linux01.gwdg.de/~pbleser/rpm-navigation.php?cat=System/inotify-tools
(2.2 is built and underway)

What is that patch doing ? :)

Also, consider using createrepo --cache

cheers
