Sure, you could do this in Perl.  It wouldn't be that difficult. 
However, there already are utilities to do this using AppleDouble.  We
would need to merge functionality.  I can take this project after my
exploration of lastdid.  Of course, I was really hoping I could get one
or two people to help me with AFP 3.0 (especially someone willing to do
some work with Unicode).
