Yes I know and use theano for some deep learning experiments. This is really a great tool. But theano will probably never be considered a default dependency for common machine learning libs as long as there is no good OpenCL runtime opensource and pre-packaged in major posix distros (linux and bsd, osx already has opencl by default but not opensource hence cannot be reused in linux AFAIK).
