The first language we implemented was Java/Scala, largely because of the excellent libraries like Mahout and Weka easily available in Maven Central. But even though the code is there in maven, it is still not trivial to deploy those algorithms as a service. We are trying to make that easier, while at the same time supporting the developers of those libraries in the process.
Being able to run the code locally is in the plans. For the most part, the algorithms in our system are already simply maven packages, or ruby gems, npm packages, etc. Being able to distribute them in binary form is definitely possible. We're still figuring things out right now, but our focus is always on doing right by the algorithm development community.
