Just to clear up this issue once and for all: The U.S. version of 4th Dimension, sold by ACIUS, does not have key disk protection. It does, however, broadcast its serial number over an AppleTalk-protocol network and prevent copies of itself from booting. The same sort of protection is present in 4D Calc and 4D Write, the spreadsheet and word processing add-ons (which are very nice, by the way). Many other programs use this same kind of broadcast scheme. The 4D Compiler is key-disk protected. Versions of 4D marketed by ACI worldwide are key-disk protected; I believe this includes those sold in Canada.
