Master/Slave synchronous data transfer in Unity

I have a master PC and several slave PCs. What I need to do is to send a send a string from the slaves to the master. But that data should be synchronous with the master. Is there a way to do that in Unity.

Don't need read this part if you understand the part above. What I have is two Kinect sensors connected to two different computers. Each Kinect logs the body frame data (a string of joint coordinates). I need to send this string of data to one PC synchronous with the other (since the other is also having a similar type of data logging locally)

Thank you in advance :D
