In terms of broadcasting, seriously do not get your hopes up, 99.<9000 chance it will not be legal to use broadcasting for any function other than utility buy ask away

But yes may as well ask everything.

Can we broadcast to resize windows ("settings" is a loose term, fucking flowchart)
Can we broadcast to join fleet, trade, open windows (wallet, etc)

Can we use VFX and menus, clickbars, as long as each individual command is sent to a single client as in the case of round robin. (As long as we don't chain together commands, i.e. client 1 clicks somewhere in window, client 2 receives click and then transfers the same command to client 3...chain)
Do we have any assurances that CCP will not ban us from some monkey seeing x characters logged on in game and reporting us out of spite
How accurate are CCP's detection methods, not that we want to (or should try to) circumvent them, just want assurance that someone with a good setup isnt banned because they're faster than the average F1 monkey

Will we get compensation if we do get banned unfairly
