Vip re(mix) = a mix of a tune that is given only to selected djs (at least at first) on dubplates, cd or by AIM (sometimes only a few copies, as in 2-5 are made). They rarely end up in wider distribution.
A dj that drops a VIP of a popular tune will count on the crowd going wild to hear this privileged version.
Vip mix = a mix of mostly vip tunes.
