I have an example of finger replication in my OpenInput module that you could reference, when its cross platform I have to drop Valve official compression and self replicate the finger transforms (for index controllers / skeletal input), its not all that hard to adapt to any skeletal input (may end up doing that in the future).
That is at 5htz (5 times a second) update rate over the network with smoothing, the right side hand is replicated and the left side hand is local. I default it to 10htz but wanted to show a lower speed one for examples sake.
