For example using cavewhere on the last 3 week expedition, I was able to create working cave maps on the same day as the survey. I even did it on small 8" windows tablet. It was great because we had working maps to use on the very next day. I'm not talking small cave either. We probably map around ~10km per expo. 

It was and it is. So nobody use it in cave. 

But imagine you survey enough splay shots they define the space around a station and  you’ll receive automatically contours of passage let’s say projected to horizontal and vertical plain (map and profile (+cross-section)). Another splay shot will define exact position of an object, etc, etc. Is this concept usable in cave? I think with OpenGL and power of recent ruggedized tablets yes, it should be.

PocketTopo is super, because you have working map immediately. More: you may use simple export from PocketTopo or better TopParser and import your day work to Survex or better Therion and connect all daily surveys of all teams together. And more: if you synchronize PocketTopo data on all PDAs or tablets of all teams they all should have identical working map next day. If you open (or create new, save it and reopen) a file in PocketTopo, it will load all other data files which are in particular folder too. But only that first one will be editable. TopoDroid is to much complicated for me.

> I guess I'm confused about how "NSS way" differs from other cave survey. Specifically, what am I missing? Are you talking about digital survey with TopoDroid or PocketTopo? 

No, mostly the order od data you survey etc. Simply surveying habit. It is different in different parts of Earth and different teams.

7-8 years is veeery long time in life of a software ;)
