[dcc2] dcc multiuser chat

[peter green]

mayube thier should eb a deny inviteing flag in a chat when it is first
established

this would allow aviodence of the particular situation you mention

the biggest use i say for multiway dcc chat is bringing together your
friends from different nets say i have a friend on undernet a friend on
quakenet and wan't to bring the 3 of us together for a private chat

there needs to be some form of control, leaving the chat by choice might
JUST be good enough.

Lets consider this hypothetical situation. A bot supports DCC2 chats. Part
of the spec is multi user chats.

User A is socially engineered to invite user B into their private encrypted
chat with a bot. User B then joins the multi user chat, the bot is powerless
to do anything (short of 'leave' the conversation maybe) and user B could
then have access to all the bot's commands. At worst, if the bot leaves,
user B has created a denial of service causing the user A's connection to
the bot to be servered.

Surely, for multi user chats, IRC channels should be used, this does seem a
lot like re-inventing the wheel, and going to the point of embedding a fully
functional IM client within an irc client which can already access perfectly
good chat networks.

Thanks,
Craig
