Having many tools available to you whatever the job is an asset. If the connection to wi-fi is strong and stable and you have a good use for it why not take advantage. I have worked with video guys that do live video feeds over wi-fi so family all over the world can see parts of the reception live and i am not too anal to give them a live feed of my mixer so they can have better sound to go with their videos. Because of this I have booked gigs because the video/photo guy has requested/refered me to their client and visa versa...
