Plugin channels are implemented using packet 0xFA, allowing client mods and server plugins to communicate without cluttering up chat. This post by Dinnerbone is a good introduction and basic documentation.

Channels internal to Minecraft
As of 1.3, Minecraft itself started using plugin channels to implement new features. These internal channel names are prefixed by MC|.
MC|BEdit
Client to server
When a player edits an unsigned book.
This payload is simply a set of bytes corresponding to an ItemStack. It is serialized / deserialized exactly the same as itemstacks in packets.
MC|BSign
Client to server
When a player signs a book. This payload is simply a set of bytes corresponding to an ItemStack. It is serialized / deserialized exactly the same as itemstacks in packets.
MC|TPack
Two-Way
Remote texture packs. This contains a string representing the url to get the texture pack from, followed by null (\0000) and then '16'.
MC|TrList
Two-Way
The list of trades a villager NPC is offering.
MC|TrSel
Client to server
When a player selects a specific trade offered by a villager NPC. It contains a single int id corresponding to the selected slot int the players current (trading) inventory.
Notable community plugin channels
Channels listed in this section are not Mojang-sanctioned. This is just a likely-incomplete list of channels used by mods/plugins popular within the Minecraft community.
