Alvaro,
The Kamap guys have been investigating doing something similar with the pgdjikstra module. I'd highly advise reading through some of the topics in http://lists.maptools.org/pipermail/ka-map-users/2006-January/thread.html
to gain an understanding of some of the problems faced when doing dynamic overlays.
I also did a post on my blog at http://chris.narx.net/2006/02/05/adding-routing-overlays-to-kamap/ which may give you some further insight.

Subject: [Geoserver-users] GeoServer + PostGis + Pgdijkstra Routing Module
I've integrated Pgdijkstra Routing Module with PostGis. I've done some
tests, with PgAdmin. I've loaded some streets, and tried "shortest_path"
function between two sites and worked very well, as I obtained a list of
four streets with their "geom" data as MultiLineString.
My problem, maybe, is related with the fact that i don't know very well
how GeoServer works with, for example, MapBuilder as client. What i want
to do is having a web page with a map, streets, inside it and a litle
form where you can ask for the shortest route between two streets. And
you have to recive as response the map with a MultiLineString layer,
drawing the result obtained from PostGis, over the Map, and perhaps the
list of the streets and the length for them, this is obtained from
"shortest_path" function.
Thanks everyone.
PD: Sorry for my english.
