But it turns out that these users included pstricks in their Beamer source, and then compiled with pdflatex. Of course pstricks requires compiling with Latex --> dvips --> ps2pdf. This worked fine for them.

I don't think illustrations (even eps --- modern pdflatex can convert file.eps->file-eps-converted-to.pdf on the fly) are a problem. It's pstricks that can give the problem when compiling with pdflatex.

I'm actually intrigued with the (limited?) ability of pstricks use with pdflatex using the [pdf] option as long as you use --shell-escape. You learn something new every day!

Good Luck,
