I have just started to look at NeuroLab to see what it can do. Is RSI the only indicator available. I suppose it would be very difficult to work with crossovers, etc.

Of course not. How did you come to this conclusion? Mostly any custom DataSeries or formal indicator can be used with Neuro-Lab. Even the included sample networks "Broad Markets" and "Patterns" show how to use ROC and a custom DataSeries created on-the-fly in Input scripts (respectively).
