BotNet Invite Script v4.1 (for eggdrop v1.3.0+, tested on 1.3.9)
by Lefty <lefty@acd.net>

This script was designed to allow bots to securely (well,
as securly as I could think of) to invite each other to +i
channels over the botnet.

It works like this.  It sets a random number code and changes
it every 10 minutes.  In order for a bot to be invited to the
channel it sends a INFO REQUEST to all bots that are +I in
it's userlist.  Then that bots sends back the code if it it in
the channel and has ops.

Here is the secure part.  The bot that needs invite must CTCP the
invite request to the other bot.  This lets the other bot check
to see if the userhost matches, and that the code is correct (so
a spoofer couldn't just do a /ctcp bot INV #channel) for bot
verification.  The upside of the CTCP is that when there is a split
the inviting bot won't be inviting someone that isn't the real bot
or inviting someone that isn't there.  The downside it that it is
only as fast as the lag between the bots.
