Power over Ethernet (PoE) can supply almost 13W of power (maximum).  I
am not sure if that is really an option or being considered for the
next USRP, but it is a potential solution for delivering power to
remote devices.

PCIe still has an advantage of much higher speeds and much lower
latency.  On the flip side, you can't put it 100m away.
