Do I need to get rid of iPhoto for storing/accessing photos on wifi network?

My wife is a food blogger and takes 1000s of pictures a week. Our iPhoto library is close to 400gbs. I just converted her MacBook to an SSD to improve performance and the plan is to just store the most recent month's photos on the MacBook and put the rest on an NAS. We previously tried a USB hard drive to do this and it was much too frustrating for 2 reasons. One, we back up everything via crashplan so it was a pain to always make sure it was plugged into her MB as she would carry it around from the office, living room, kitchen, etc. We also have 3 young boys so portable hard drives plugged into a laptop that is always at arms reach is a recipe for disaster. (Already had one ruined because of that) So we need some sort of wireless option. We understand it may be slower, but we won't access those files very often so it's not a huge deal. Everything I've read about various NASs (Synology, My Cloud, etc.) all say they don't work too well with IPhoto/Apeture. (Currently use iPhoto) So any recommendations on better options? I want something fairly simple for her. What about transitioning to Lightroom or non-Apple to allow easier remote storage and access? Anyone have any success with wireless remote storage/access of iPhoto?

Thanks!
