+==========
+
+ o Remove the big switch statement from the function
+ silc_server_packet_parse_type and replace it with predefined
+ table of function pointers where each of the slot in table
+ represents the packet type value.
+
+ Same could be done with notify packets which has big switch
+ statement too. Same kind of table of notify callbacks could be
+ done as well.
+
+ o The parser callback in the server will add a timeout task for
+ all packets. It will require registering and allocating a
+ new task to the SilcSchedule. Maybe, at least, for server
+ and router packets the parser would be called immediately
+ instead of adding it to the scheduler with 0 timeout. It
+ should be analyzed too how slow the task registering process
+ actually is, and find out ways to optimize it.
+
+ o The SERVER_SIGNOFF notify handing is not optimal, because it'll
+ cause sending of multiple SIGNOFF notify's instead of the one
+ SERVER_SIGNOFF notify that the server received. This should be
+ optimized so that the only SERVER_SIGNOFF is sent and not
+ SIGNOFF of notify at all (using SIGNOFF takes the idea about
+ SERVER_SIGNOFF away entirely).
+
+ o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
+ sent to a client if it is on same channel as the client that
+ signoffed. However, the entire SERVER_SIGNOFF list is sent to
+ the client, ie. it may receive clients that was not on the
+ same channel. This is actually against the specs. It must be
+ done per channel. It shouldn't receive the whole list just
+ because one client happened to be on same channel.
+
+ o MAYBE: The SilcChannelClientEntry can be:
+ SilcUInt32 address;
+ SilcUInt32 mode;
+
+ where address is SilcClientEntry address XOR SilcChannelEntry.
+ You can get SilcClientEntry by doing client = chl->address XOR channel,
+ and SilcChannelEntry by doing channel = chl->address XOR client.
+ As long as the other pointer is always available when accessing the
+ structure this can be done.
+
+ o Add reference counters to all Silc*Entry structures
+
+ o SERVICEs support (plugin, SIM)
+
+ o If client's public key is saved in the server (and doing public key
+ authentication) then the hostname and the username information could
+ be taken from the public key. Should be a configuration option!
+
+ o Add a timeout to handling incoming JOIN commands. It should be
+ enforced that JOIN command is executed only once in a second or two
+ seconds. Now it is possible to accept n incoming JOIN commands
+ and process them without any timeouts. THis must be employed because
+ each JOIN command will create and distribute the new channel key
+ to everybody on the channel (Fix this to 0.9.x).
