Here's my ideas for a FFB.  18 or 20 bands, 1 octave apart for the 
highest and lowest bands, 1/3 octave or less apart in the middle.
Individual outputs for each band and an envelope follower for each 
band as well with the follower response tuned to that particular 
frequency range.  A follower output for each band as well.
This thing could be used as a front end for a vocoder.  A second one 
with the addition of a bunch of VCAs could be the back end of a 
vocoder.  You could split a sound into a bunch of bands and 
manipulate each band differently.
I'd love to hear others ideas on this thing as well.
