I2C Design Mathematics: Capacitance and Resistance
The capacitive coupling between the I 2 C signal lines and the ground plane can be significant if the ICs are far from each other, or multiple ICs are on the I 2 C bus. For long runs, separate the I 2 C lines from one another by several trace widths (or place the Vdd and ground traces between the signal traces) to reduce capacitive …

AC-coupling capacitors for high-speed differential interfaces
Any AC coupling capacitor that you place in your signal line is going to be a lower impedance point and will therefor cause a negative reflection back to the source. Whether or not this reflection will come back and then interfere with other bits is determined by the speed of your signal and the distance of this reflection point from your transmitter.
