How well do these shades work for Inside Mount vs Outside Mount? On the Inside Mount, how much of a gap is there between the shade and the window frame?

There are some variables involved. For one thing, if your dealer makes an inside measurement, the HunterDouglas fabricator will take 3/8" off that measurement. That means there is automatically a 3/16" gap on each side. Then, the fabric falls about 1/8" or a tiny bit more inside the head rail width on each side. So, as apnar stated, you're likely looking at a bit over 1/4". If you want to get gutsy, you can have the dealer overstate the width by a little bit, say 1/4" to compensate for the automatic reduction, but you're taking chances. These deductions are to compensate for out of square window frames, uneven window frames, etc., so they are there for good reason.
I far prefer to build light baffles in back of and in front of the shade as necessary rather than believe I could get them tight enough not to leak. This way, you can stop virtually 100% of the light. I find that any light leakage whatsoever is unacceptable. Even a slight sliver of light becomes gigantic in a 100% darkened room.
Even outside mounts need some sort of baffling (my prefered mounting approach for blackout). The back side of the shades are always white. Light hits that and bounces back to the wall, then into the room. While light doesn't turn corners, it sure bounces around a lot.
In all of this, I am assuming a 100% dark room such as is desired for front projection. If you're using some other type display device and have low level lighting in room at all times, your demands at the window are reduced a little bit.
