So I found out something pretty cool about remote play. While using remote play, you can use the PS3 Golds headset (probably the elites or any other usb PS4 compatible headset as well) wireless as if you were playing directly on the quad, but with your vita. Though in order to do it, you HAVE TO cut on remote play and have completely up on the vita before turning on the headset (you can leave the usb dongle in the quad, just have the Golds turned off). If you try to do it backwards, or cut the golds on before the vita is fully connected thru remote play, the User prompt for the headset will block the vita from connecting successfully to the quad and will not connect until you turn off the headset.
Also, don't know if it's been mentioned before, but remote play on the vita does not interrupt any game you're playing natively on the vita, so you can pause whatever you're playing on the vita and connect to remote play, play whatever from the quad on there and when you're finish, you can go right back where you left off on your vita games.
