  I do not truly understand the question (nor the interest to proceed this
way...) In any case, as you said that you have already some code to compute
what you need, I do not see what is the change with \psshadowbox. You must be
able to consider it as a TeX box like others:

\documentclass[a4paper]{article}

\usepackage{pstricks}

\pagestyle{empty}

\begin{document}

\psframebox[framesep=0,linecolor=red]{\Huge Hello!}
\hfill
\psframebox[framesep=0,linecolor=red]{%
  \psshadowbox[shadowsize=0.5,linewidth=1]{\Huge Hello!}}

\end{document}


  Anyway, I never build a poster (!), but I would certainely not follow this
direction. In general, computing absolute positions is long, painful, error
proning and absolutely not flexible, ever you use a serie of \rput commands
or of the `textpos' package.

  I believe that the "psmatrix" environment is a lot more powerful and
flexible for such needs.
