Through-zero phasing, huh?  What would that sound like?  Sounds like an
eventual Csound project for me.  I found a paper by Mike Beigel (one of
the Mutron guys) that describes how to implement allpass stages
digitally, how the coefficients correspond to RC products, and so on. 
Very nice - especially when I have the RC products from EN #43 to create
an allpass Dome filter for frequency shifting.  I'm in a class at the
University of Washington to learn Csound, so I will keep people on this
list posted on any progress I make (as long as no one objects to the
occasional digital DIY comments).
