***Please lock this topic if I've just been stupid and there already are hooks for onWriteToNBT and onReadFromNBT.***

What I think would be a good addition to Minecraft Forge are hooks so that you can write additional data to entities. For example I am currently writing a mod that adds warmth to the game, and trying to write the warmth level into the player's NBT, however I can't figure out a way to do this unless there's a way to detect when the NBT is being written to/read from.
Thanks for reading.
