About multiple iPads connecting to one mac(max patch) using Mira

Since we can not define specific iPad IP address for Mira to send or receive, when dealing with one mac using mira to receive multiple iPads motion data, it seems not a straight forward procedure. Though, Mira does provide "Device Identifier" at the end of each mo. module, I can use zl.rev and a simple work around to get motion sensor data from a specific iPad. I just wonder if there is any better ways to do that. Since I noticed that there might be slightly dropped or delayed performance when receiving motion sensors from multiple iPads simultaneously. Not sure it's an issue of my patch or not. Please give me some advice.

Besides, maybe this has been required many times here, that to specify a unique IP to an iPad so that we could control certain interface appearance and interaction on a certain iPad when dealing with multiple iPads. Since right now, each iPad shares the exact same interface from one Max patch, this is quite problematic during group performance.
