Fair enough :-).

This is the beauty of some Unix email clients; you can completely customize
things like the attribution.

Great. I'd be interested in seeing them. 

Most academics consider the linear phase FIR design pretty much a dead 
field. I disagree with this view in that filters with larger numbers of
coefficients (256 to 1024 and more), with large stop band attentuations 
(-100dB and greater) and very narrow transition bands are still extremely 
difficult to design with all of the known methods.
