I think that a luatex solution should be easy (for Hans, hint hint).

Collect everything on a page, and do some attribute magic to reveal it one 
by one (or change colors, etc). Personally, I occasionally use a primitive 
and ugly solution

\StartSteps{4}
\startitemize
  \item ...
  \2{\item ...}
  \3{\item ...}
  \4{\item ...}
\stopitemize
\StopSteps

where \StartSteps collects its body, typesets it 4 times. In the first 
iteration, \1 = \donoting, everything else is \gobbleoneargument; in the 
2nd iteration, \1 and \2 = \donothing and so on.
