RTCM transformation would be great update, excpecialy when neede to stake points.
In Serbia, there is one NTRIP service that provides RTCM transformation ( datum and projection information, 7 parameters Helmert transformation, horizontal and vertical grid shift using bi-cubic i terpolation).
I have tried to use this service connecting to NTRIP using Fieldgenius, but only 7 parameters transformation is applied, no grid shift.
I know that Reach View 2 doesn’t support RTCM transformation for now. Does that limits FG functionality ir not? 
I think that connecting to NTRIP using FG, and FG applying corrections and transformation to measured wgs84 coordinates will overpass RV2 limitations.
