This is possibly a silly question, but is a base 15 ReCo "move a person instantly 50 paces" actual teleportation, or does the magus need to move through the intervening space (albeit it too fast for anyone to notice).
If it is teleportation, then they can get in and out of locked rooms (or at least bars too tight to squeeze through). But no clothes or other non-Corpus gear.
If it moves through intervening space, then the moved person probably drags their clothes and any other non-encumbering item they have a very strong attachment to. And they can probably arrive at their destination in any orientation they choose - eg prone on the back to standing threateningly behind a potential victim (I would expect a very high Finesse roll needed).
Just for fun, I wonder if I can make a Magus with Mythic Blood who is descended from an Enchanter named Tim that is supposed to have accompanied King Arthur and his knights on the quest for the Holy Grail, in one obscure telling of the legend. The Mythic Blood inherent power is silent ReCo15 move 50 paces, and the focus is in creating bursts of flame 
Another question occurs to me. How does foreign auras and Aegis of the Hearth affect the inherent power of Mythic Blood?
