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.

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 ;)
