+ * The Rate Limiting System, An Abridged Guide to Nonsense.
+ *
+ * OSCAR defines several 'rate classes'. Each class has seperate
+ * rate limiting properties (limit level, alert level, disconnect
+ * level, etc), and a set of SNAC family/type pairs associated with
+ * it. The rate classes, their limiting properties, and the definitions
+ * of which SNACs are belong to which class, are defined in the
+ * Rate Response packet at login to each host.
+ *
+ * Logically, all rate offenses within one class count against further
+ * offenses for other SNACs in the same class (ie, sending messages
+ * too fast will limit the number of user info requests you can send,
+ * since those two SNACs are in the same rate class).
+ *
+ * Since the rate classes are defined dynamically at login, the values
+ * below may change. But they seem to be fairly constant.
+ *
+ * Currently, BOS defines five rate classes, with the commonly used
+ * members as follows...
+ *
+ * Rate class 0x0001:
+ * - Everything thats not in any of the other classes
+ *
+ * Rate class 0x0002:
+ * - Buddy list add/remove
+ * - Permit list add/remove
+ * - Deny list add/remove
+ *
+ * Rate class 0x0003:
+ * - User information requests
+ * - Outgoing ICBMs
+ *
+ * Rate class 0x0004:
+ * - A few unknowns: 2/9, 2/b, and f/2
+ *
+ * Rate class 0x0005:
+ * - Chat room create
+ * - Outgoing chat ICBMs
+ *
+ * The only other thing of note is that class 5 (chat) has slightly looser
+ * limiting properties than class 3 (normal messages). But thats just a
+ * small bit of trivia for you.
+ *
+ * The last thing that needs to be learned about the rate limiting
+ * system is how the actual numbers relate to the passing of time. This
+ * seems to be a big mystery.
