Ask HN: I wrote an XMLA cube server that connects SQL datasources. What's next?

I wrote an Excel compatible XMLA server that translates MDX to SQL and allows to easily define a cube, load data and expose it in Excel.

Now I am thinking about the next feasible development milestone also with monetization in mind.

a) integrate an in memory database layer and some basic ETL functioniality and make a SSAS like product offering?

b) create several standalone BI products from it by connecting it to individual vendor apis?

c) offer it as an OLAP provider for big data systems like Apache Kylin or Hive?

What comes to your mind? What would you do?
