[VANILLA-L:983] Re: metaserver is reborn

Current action plans;
	- awaiting propogation of DNS name changes for metaservers,
	- awaiting patches to clients to adopt CNAME for metaservers,
	- proposing patch to clients that will look up each metaserver,
	- request server gods on 2.8pl0 or later to use solicitation.

Future development plans:
	- add UDP player list and echo reply to Vanilla server daemonII,
	- add ping times to client metaserver list,

There's nothing wrong with this.  It's your problem for logging.
Compared with you polling their server every 5 minutes, the packet load
is minimal.  Only one server is soliciting your metaserver; a pity.

Remember; if your metaserver polls a server you are up for their MOTD
coming down your line.  If their server informs you, it's just a tiny
set of packets.

Also, the metaserver code has a de-listing feature in case the frequency
is upped beyond the ntserv/solicit.c coded limits at the server end. 
Have a read of the code around there.

(a) no, the metaserver has NOT sent a packet, it received it only,
(b) lag from the server to metaserver is not useful data to a player,
as Alec Habig stated,
(c) other players lag is not relevant to a new player.

I believe, as I have said before, that the Vanilla server should have a
player list UDP port which returns part of the packet sent to it by a
client, and so the client can calculate ping times and display them
graphically on the metaserver list.
