Nobody has a t-tap yet, as it’s unreleased, so can’t say for sure. But I agree with Jeremy; the IoXT should be able to run all NLEs using their current driver set without setting up different boot partitions. If I’m not mistaken it will even run Avid in addition to FCS3, FCPX, and PPCS6.
It’s one of the reasons AJA products are 3 times as expensive as Matrox.
