There is a regexp-replace command 
   M-x query_replace_match
With (the extended) cua-emulation it is on Ctrl-F P, try Help>Show_Key
query_replace_match to find out what it is bound to in your setting.

Jed's regexps are somewhat limited in relation to perl or sed, so the
question is still of interest:

For people on UNIX, there is the process_region() command in pipe.sl. You
might have to activate it with
  autoload("process_region", "pipe");
in your .jedrc.  

With the ishell mode from jedmodes.sf.net/mode/ishell comes a command
shell_cmd_on_region that can do what you want:

 SYNOPSIS
  Save region to a temp file and run a command on it

With a keybinding like
  setkey("shell_cmd_on_region(,2)", "^FX");
you would have it replace the region with the result of a command asked
for in the minibuffer.
