Allow Custom Mode Spectate without delay?

It feels really frustrating when you want to watch a friend play and talk to them. I realize that this can be easily abused in normal games but can we allow people to not have delay in Custom games? Of course some custom games should still have delay, but what if the owner of the room could allow people to specifically not have the delay, we can have a little sign next to the spectators if the owner has decided that they won't get a delay. This will accomplish the following things

1)Friends can talk to each other while one of them is in a custom game and comment on the game 2)If the owner of the room want's to pull shenanigans by having a friend cheat, everyone in the room will know 3)Even if the owner doesn't want to cheat we can limit it so that the friend spectating can only see one side's perspective

What do you guys think?
