I have the TeX installation of Gerben Wierda, on Mac OS X 10.3, but I 
wanted to experiment your suggestion of
\definefont[BBMFont][bbm12 sa *]
\def\Bbm#1%
  {{\hbox{\BBMFont #1}}}
However the result of ${\Bbm R}$ is not a blackboard bold R, but some 
other character resembling the delimiter |.
Actually with ConTeXt there are many fonts that I can't use correctely...

In any case thank you for your insight.
