Yes, it does sound familiar.

From the multi-config.postinst file from that source,
I did create the attached HWaddr based preseed shell script.

To use it, you must have a web server ( even the most simple HTTP server
will do fine ) Put on the webserver, hostname ws, minimal 3 files:

 * preseed.cfg with at least a line that contains
 d-i preseed/run string hwaddrbasedpreseed.sh

 * hwaddrbasedpreseed.sh, the attached script

 * hwaddr-00-B0-B0-FE-EE-ED.cfg with host specific preseed information

in the directory d-i/etch

Start debian-installer like this

 install auto url=ws

The 'auto' parameter will postpone the language and keyboard question.
And 'url=ws' expands into "http://ws/d-i/etch/preseed.cfg";, in that
file is the clue to start the hardware address based preseed script,
which gets the hwaddr-00-B0-B0-FE-EE-ED.cfg file.

This way you can (re)configure a host based on his hardware address,
without access to DHCP server configuration.
And even without the hassle of remastering a CD-ROM, without
carring a floppy along the installer CD.
