@FordLawnmower -- Nice job here. I used it briefly on my Eggdrop before I accidentally rm -r'd my /var/lib/ on my VPS. It responded almost instantly, and the lag was due to the VPS restrictions, not your TCL.
@jaytea -- So have $1 sync to $2 and $2 sync to $1? Or have it unset bans in $1 that match bans in $2? Both seem plausible and very possible. Explain more if I'm mistaken, please; it's 2:31 AM here. :)
