Here's a version of my Virtual DJ 6 (I haven't really tested it in 7) mappings for the VMS4. Everything seems to work just fine with exception to the crossfader vs. headphone cue/mix volume. All the controls seem to work just fine between the controller and VDJ. the PFL lights are still out of sync since the VMS4 maintains state of the PFL (most likely a firmware thing like before). Once you're used to the PFL (cue/mix) behavior isn't not too terribly bad (unless you're a 'handsoff PC' type of person).
