The Holy Grail of Magical Research, Teleportation via Magic... why not? Options

[Earlydawn]

I'd throw a couple modifications onto that spell. First of all, give it a big drawback, Terminator-style.. the mage only teleports with objects that are actually bound to his Essence - flesh, implants (they're "interfaced" with the meat, albeit messily), etc. Secondly, as the range became greater, the point-jump accuracy decreases. Teleporting a click away will likely put you in the alley you're imagining, but going from the UCAS to the U.K. will require a skillful mage to ensure you even end up in the same province. You can burn net hits to pull in the diameter of fluctuation that the GM has to work with, but then you can't juice your range. As you said, drain gets doubled for every rule you break (one at a time, nothing comes with you, and so on). Broken concentration during casting leads to disastrous consequences. Oh, and it's a ritual magic. No one caster should have that kind of power.

This all goes out the window when teleporting along leylines, because that's fluffy and awesome. Perhaps it should be restricted based on domains, though. You can only hook into a leyline from an area with a domain matching yours, range decided by the power of the attuned site.

Prefer a spell called Materialization, like the spirit power, to the Teleport problem. The mage still has the astral projection timer running, is dual natured during the time, and has an active spell running. We've always played that foci for spells ned to be at the location where it is cast. Not sure what drain should be in 4th, to low invites abuse. In 3rd it was Deadly+2 drain with the force of the spell needing to be equal the the str of the spirit you wanted to materialize as.

Nah, take a Spirit Pact with a free spirit. He gets to cast your Orgy spell (he gets a kick out of it), and you get his Materialization power.
