Try the OLS (Ottawa Linux Symposium) 2003 UDEV presentation paper by..
none other than our own.. Greg KH.  I believe that's where I saw it. 
(I discovered that paper in coverage of OLS.)

For practical implementation examples a bit closer to home, check out the
SCSI and IDE UDEV configurations on any UDEV Gentoo system.  They provide
some pretty strong and practical examples of several of the features the
paper talks about, including dynamic symlinking for multiple entries, and
calling an external program then using its output to provide device names,
in this case, to provide DEVFS compatibility, since that's what Gentoo had
standardized on.  (Here, I ripped out that stuff for my IDE drives, and
only retained the traditional /dev/hdX entries.  I had to change the
hdparm config a bit as it used the DEVFS entries and I used it, but that
wasn't a big deal either, since I already knew the UDEV basics from the
paper and following the Gentoo scripts wasn't difficult.)
