That is an irrelevant argument. Whether or not psychic abilities and magical abilities use the same source of energy is not of concern. In most systems or beliefs, magical power and psychic power are interchangeable, with only the fewest abilities making each unique.
In Shadowrun, Magic is tied to the Mana Sphere. Period. End of Sentence. If you take a mage to geosync orbit and he tries to cast a spell then he is screwed. A technomancer is on the same shuttle and he uses his abilities... no problem. THAT is the difference. Nothing more, nothing less.
So Neraph, how is the Technomancer powering his abilities? How can an unaugmented human brain generate enough radio waves to communicate with the Matrix? We know it's not magic because it works in Mana voids and Mana warps without any modification. When you can answer that in a manner that is logical for the game universe, then I'll drop my belief that Technomancers are psionic.
