Hi Dan, Sounds like some 360 pano project... A good server is critical, especially if you have more of these pano's loading. On a past project I was working on, the chunk loading option was not even necessary due to this server. But for slower connections, indeed loading just what you see, say an imageslice per quadrant does help.
Also, if you export via photoshop/export for webdevices as jpg. Even at 80 compression at sizes of 4096x4096 you indeed very often sizes as yours. I've wrote a little php using the gd2.dll, and turns out if I do export from photoshop lossly, once i run my script, the file weights lower than 1/2 of photoshop size. with no visible diffs. A good idea is of course to automate, my php for instance applies on a full directory you pass to it. If you know your way around, it should cost you max an hour of work. This little php effort is really worth it and saved me 1/2 the data on entire content. Also very similar to the uvcropping feature Prefab holds, a tiltcropping is often a way to minimize size for this kind of work, as you usually do not use the poles because of the distorts. most app generating these either add top/down some color strips or logos of their eye fish cameras. There too, cropping and adjust mapping with repeat and scaleY does save you 3 to 6 % of the map depending on your tilt constrains. Loading low res, is a bad idea. not only you will have to load more, but it will even slowdown processes on fast connections. Hope it helps a bit.
