Hi, Pablo !

Funny, I asked the same kind of question in a LaTeX mailing list a few days 
ago. The anwer I was given requires a LaTeX package, but is written in TeX as 
well, so it may be easy to adapt it for ConTeXt. Sorry, I cannot do that 
myself yet. I have just started to learn ConTeXt and am a very busy slow 
learner.

\usepackage{atbegshi}
\newcommand{\Repeat}{<the content you need to be repeatedt>}

\AtBeginShipout{%
	\ifodd\value{page}%
	\else\Repeat%
	\newpage%
	\fi%
}

I hope it helps. But maybe you don’t need to repeat the same page every two 
page, as I did…
