Share via LAN?

I read this in the FAQ...

"Only the GM needs to purchase Realm Works, and the GM can then show revealed information to the players during the game."

How? By having my players all get up and come look at my laptop screen? That doesn't seem feasble. The only way that they could see revealed info on their individual laptop screens is to have the player edition right? Which leads to this question..

Assuming my players all have the player edition and I have the GM edition, and we are all sitting at the same table, do we HAVE to use the cloud to update information? Or can players see my changes via a LAN?

If I decide I don't want to pay for the cloud as a GM how can I share info with my players at at the table?
