#RPCs and design of the chatbox

Introduction

Features:

• chat must not be db-heavy
• deleted messages must also disappear in the client

RPCs

• chatbox_list - list everything about chatbox
• chatbox_list_since - list messages since a given message id
• chatbox_post_msg - post chatbox message and moves oldest message to archive
• chatbox_delete - delete one or more messages

Design

This is pretty simple. There is only one table. Shouts are inserted into para_chat table. Shout insertion generate events. Shout deletions generate events. And so it goes.
