%                     \
%                      >---  pipeline3
%                     /
%       pipeline2 >--'

Right.  I was thinking of playing with file descriptors three and up.
[Nice ASCII art, BTW; not many would think to use . and ' there  :-]

% However if you use a UNXI bash shell thier was an altunative method
% And may work for you..
% 
% using UNIX bash...
%    convert miff:<(convert logo: miff:-) output.jpg
% 
% The   <(...command_pipeline )
% is a bash construct that is executed and piped into a magical
% filename which is then substitued for on the main command
% eg something like, but the command work simutaniously...
% 
%    convert logo: miff:-  >  magic_filename
%    convert miff:magic_filename  output.jpg
% 
% The magical_filename however is not a temporary file and never needs
% any form of clean up.

Right.  The problem happens when you need two or more of those along the
way...

But specifying the command at the < point might work, and thanks to ()
instead of `` the nesting might be manageable.

Or I might just bite the bullet and work with temp files :-/  I hope to
move away from the command line and to the PHP PEAR IM class anyway
(though I haven't yet done the first bit of exploration to see what doing
so entails).
