In Automator, create a new Workflow, add action Run Applescript, and replace the contents of the text box with this entire file. At the top, where it says "Service receives selected ___ in ___" select "Files or Folders" in the first drop-down menu, and "Finder.app" in the second. You can set a keyboard shortcut in System Preferences -> Keyboard …

	on run {input, parameters}

	tell application "Finder"
	set currentSelection to selection
	set currentFolder to target of front Finder window as text
	end tell

	tell application "iTerm" -- this should work if you replace "iTerm" with "Terminal" (untested)
	if currentSelection = {} then
	set thePath to POSIX path of currentFolder
