how to pipe to stdout and stderr

[Andy Spiegl <zsh.Andy@xxxxxxxxx>]

Maybe I'm just too tired right now, but I can't find the solution how to
pipe the standard output and standard error to 2 different programs.

Example:
 program foo   (prints to stdout and stderr)
  program bar1 should receive only stdout
  program bar2 should receive only stderr

How can I do this?  Someone knows how to do that in bash, too?

Thanks so much,
 Andy.
