I think so - I tried to use 'tail -f' to watch the data, and got the
correct output.

here is the configs related to xmobar:

	main = do
		xmobar <- spawnPipe "xmobar"
		xmonad $ defaultConfig {
			...
			logHook            = dynamicLogWithPP $ myPP xmobar,
			startupHook        = myStartupHook
		    }

	myPP h = defaultPP 
	    { ppCurrent = wrap "<fc=#8ae234>[" "]</fc>"
	    , ppVisible = wrap "<fc=#8ae234>" "</fc>"
	    , ppHidden = wrap "" ""
	    , ppHiddenNoWindows = \_ -> ""
	    , ppUrgent = wrap "<fc=#ff0000>" "</fc>"
	    , ppSep     = " "
	    , ppLayout  = \_ -> ""
	    , ppTitle   = wrap "<fc=#ffffff>< " " ></fc>"
	    , ppOutput = hPutStrLn h
	    }

and my .xmobarrc:

	Config { font = "xft:Wenquanyi Bitmap Song:pixelsize=12"
	       , bgColor = "black"
	       , fgColor = "grey"
	       , position = Top
	       , lowerOnStart = True
	       , commands = [ Run StdinReader
			    , Run Network "eth0" ["-L","10","-H","100","--normal","#8ae234","--high","red","-t","<rx> <tx>"] 10
			    , Run Cpu ["-L","10","-H","60","--normal","#8ae234","--high","red","-t","CPU: <total> <user>u <system>s"] 10
			    , Run Memory ["-t","MEM: <usedratio>%"] 10
			    , Run Date "%a %b %_d %H:%M:%S" "date" 10
			    , Run Battery ["-t","[<left>]"] 600 
			    , Run Mail [("mail", "~/.mail/pop3/work")]
			    , Run Com "volumn.rb" [] "vol" 10
			    , Run PipeReader "/dev/shm/lrcfifo" "lrc"
			    ]
	       , sepChar = "%"
	       , alignSep = "}{"
	       , template = "%StdinReader% }{ <fc=#8ae234>%Mail%</fc> %cpu% %memory% %eth0% %battery% [%vol%] %date%"
	       }

Thanks,
Jan
