Dear Jan, I've placed a copy of the published version of the paper at <http://socserv.socsci.mcmaster.ca/jfox/Misc/polytomous-effect-displays/inde x.html>, along with the R code for computing effects and their standard errors and R code for the graphs in the paper. As you'll see, the functions provided do not construct graphs automatically, as those in the effects package do for linear and generalized linear models. Eventually, I'd like to incorporate this material in the effects package.
