Where are resolution/Hz restrictions being enforced?
I'm curious about which component in the whole 3D setup is responsible for restricting 60Hz to max 720p and 1080p to max 24Hz. I've heard from some people that it's an HDMI restriction (implying I need a newer TV or HDMI cable), and others saying that it's an arbitrary software restriction enforced by the 3DTV Play software. What it really comes down to is 1) at this point in time, is 3D full-frame-per-eye gaming possible at 1080p/60Hz with some combination of software/hardware, and 2) if so, what would I need to get that working (i.e. no more red text scolding me for setting my game too high)?

With HDMI 2.0 it will be, but HDMI 1.4 doesn't have the bandwidth i don't think.
Maybe if they lowered the bit depth to 24 or 16? I haven't done the math, but i recently ran into the formula for calculating used bandwidth here:

Im curious as to whether we need to include the "8bit to 10bit encoding" into the equation. Also not sure about the vertical/horizontal blanking and if that area could be used for rendering.

I don't think this quite answers my question. I'm wondering whether the 3DTV Play software is detecting an incompatibility, or if it is hardcoded to always say "nope" if the resolution is set to 1080p@60Hz, even if the hardware is 100% compatible.

Short answer:
Historically, bandwidth is limited by the HDMI chip in the display. This can't change soon enough, as newer chips are already in some devices and HDMI 2.0 has kind of been agreed.
1) Yes, but not with 3d vision.
2) Dual 1080p projectors can be combined to create passive 3d, but only with tridef for gaming as far as I'm aware.

Yes, it's the bandwidth limitation of HDMI. It cannot run any faster than 24Hz in 1080p. It was designed for Blu-Ray movies, and nothing else. And it's frickin' old. The manufacturers have very little imagination, and can't see anyone doing anything in 3D other than watching movies, so pretty much all present hardware doesn't support anything higher.
As rustyk notes, it's starting to change, but you have to look closely.
Now it [i]is [/i]possible to run 1080p@120Hz today, but you have to use Dual Link DVI.
I know there are no projectors that have that connector, and I don't think any TVs do either. Only monitors. This might change soonish, because of the push for 4K TVs.

As bo3b says, it it possible via dual link DVI with an appropriate 120hz monitor.
I was only talking about HDMI.
You need to spend about 10k on a semi-commercial projector to get a dual link DVI connector. You only get HDMI, component, VGA or single link on consumer grade devices.
An exception is that some of the newer 4k projectors have a HDMI 2.0 upgrade path, but there are still questions over the details of 3d support.
Also, you can run 30Hz 3d @ 1080p over HDMI. I don't know if it's a mandated HDMI mode but it isn't available in 3dtv play. I used to use rollermod to enable it for my TV, but I think tridef lets you anyway.

Currently Sony is shipping several HDTVs (aka 'UHD 4K')that have HDMI 2.0 inputs.
Panasonic supposedly has at least one with HDMI 2.0. HDMI 2.0 can easily do 1920x1080 at 120Hz, but that does not necessarily mean that one can play a 1080p game in 3D framepacking at 60 fps per eye. The TV would have to support that 3D mode.
