Networks can be written in python in caffe recent versions

[spetafree]

Very good overview, but I think you missed a feature in caffe - Networks can be written in python in recent versions of caffe. See for example:
https://github.com/beijbom/beijbom_python_lib/blob/master/beijbom_caffe_tools.py
There is a python syntax to generate the network, which is then written to text file and re-read upon training.
