Dear Piero, The AGPL is to encourage people who develop on PredictionIO contributes back to the open community, even though they are using it to offer cloud services. We are seriously looking into the possibility of making custom engines/algorithms separated from the main server code, so that they don't need to follow AGPL.
In the meantime, if you have any specific questions or requirement in terms of licensing, please contact PredictionIO team and we'll try to work it out.
