[Q]Thinking of getting a motox GSM Unlocked for Tmobile but have newbie questions topic

I going thinking of jumping on that 100 coupon for motox but i had some questions.

1.I see a ton of roms for the nexus 5 but What Roms are actually being work on for the T mobile Moto X , i been looking around but i keep seeing them for different carriers only

2. Is there a way to get wifi tethering?

3 is it hard to unlock the bootloader?

4. lol Any regrets so far getting the motox instead of the nexus 5 ?

5 Has rom development increased recently with the price getting lower?

6. [non motox question] but is there something that exist to disable power button when a pin password is active . My last phone got stolen and i really wish there was some way to disable the power button so who ever takes it has no way to power it down and would been nice if i could of track it.

I love the features on the motox that the nexus doesnt have so thats why im lending towards it . but just alittle worried on how little rom development there is for future sake
