Just needed to do more homework. The thing to do in my situation
is to override the 'completenames' method of cmd. The method below
completes all executeables in the path just like bash.

What confused the hell out of me is I couldn't get 'completedefault'
to do anything. Viewing the cmd modules showed that is only
run when the completer index is > 0. Thus, 'commands' (the beginning of
a line) is run against completenames... 

def completenames(self, text, line, begidx, endidx):
	l = cmd.Cmd.completenames(self, text, line, begidx, endidx)
	path = os.environ['PATH'].split(':')
	textlen = len(text)
	for dir in path:
		try:
			files = os.listdir(dir)
		except:
			continue
		for file in files:
			if textlen > 0 and file[:textlen] != text:
				continue
			if os.access(dir+'/'+file, os.X_OK):
				l += [file]
	return l
