Temporary IP Expemtion?

[Estolcles]

Question:

I'm outfitting my Office/Man Cave/Garage so it has wireless internet. I have a handful of riends IRL who also are on the p99 server. Normally we all play from our homes, but I was thinking of having a straight up nerd-out, and breaking in my garage with food, drinks, and EQ-ing on p99 (maybe even raiding some middle level zones just because we're all there and can communicate without typing).

My question is: Since they already have pre-existing accounts, with attached IP's. If they bring their comps over, do I need to get an IP exemption done before hand so I know it's done in time for the partying/"being nerds" OR because those same comps will be using the same files, just logging on from a different location, it'll all work without hassle?

Kinda clueless to the intricities of the net in cases like this, so any help would be appreciated.
