I think it's not a difficult change: call PvCameraOpenByAddr if given an IP address, or PvCameraOpen if a unique ID - but with that I've exhausted my knowledge of the Prosilica API.  Perhaps I'll give it a try and see if there are problems (functionality/performance limitations?).

This is convenient because cameras can use DHCP and do not need a fixed IP address.  But it won't work across subnets because it requires a broadcast to find the cameras by Unique ID. We could modify the driver to add logic to allow IP address or IP name in place of Unique ID.
