lay2 is just fine - it's a clientside command, great for laying money (the npcserver requires that you actually have the money before laying it, it will be deducted from your rupees) or other stuff from the game engine

You will probably want two event blocks: one for playerchats which tokenizes the chat text and sets a string to #t(1), and a second which checks the mousedown event, checks the status of the rightmousebutton flag, and does your lay2.
