So i used to use synergy, but it always required 1 server pc, and then client pc's.   When synergy 2 came out, it allowed all pc's to be client and server which was great/exactly what I was looking for. 

Unfortunately with the newest windows version, synergy 2 went down, and while its supposed to come back - theres no eta.   

this left me looking for another solution as I work across 3 pc's and often need to be at any of the 3 while not scooting back and forth across the room to access them from one another.

Enter - Mouse without borders.   This has largely done what I need it to do.   Apart from some wonky behavior when I restart one of the pcs, and abysmal handling of file transfers, its been without fail.

still ive always been a huge proponent of groupy, and I'd like to try some other stardock applications.  Seems like it could be a good fit.  

My question is this.  If i have 3 pc's, and I have a keyboard and mouse at all 3.  Can I use any of the pc's to control any of the others seamlessly?  A/B/C      A would obviously be able to control B and C.   But could B control A/C or C control A/B?   

aka are they all client and server?
