Currently, Vegas can only edit 2D 360 footage to the best of my knowledge. That said, the camera you mention only has one lens per side, so actual 3D wouldn't be possible then, even though it does capture a 360 degree image. So, have you tried editing the footage from this camera in Vegas?
Once you have equirectangular projections you can edit VR180 using the existing 3D tools.
I've tinkered a bit using the dual fisheye affect introduced in V16 to create the equirectangular projections from a side-by-side vr180 camera in this thread:
