Is there any chance that you will abstract from NodeJS/Mongo solution?

Right now this board is the only reason to setup NodeJS/Mongo/Cube, so no reason to use for me right now. But in case of differ solution - i would glad to use it :)

I don't really see other solution.

Cube depends on NodeJS and Mongo to works, and ResqueBoard depends on Cube.
Cube is a really great tool for computing metrics, a lot of metrics, and in realtime.

All realtime events are handled by NodeJS, and the Mongo is a very fast and scalable database.

There's no way to move away from NodeJS, or your server will take a hit with the big number of request/min.
"big data" storage are needed to store the hundred of events per minute. Mongo is already the most accessible and easy to use storage.

With 1 million jobs, my database is now around 12Gb. There's simply no way other classic storage engine can handle that, in realtime.
