great so lets sit down and see how we can collaborate on this. Let us 
know when you are in Berlin as we are there for the whole period. We can 
sit down with Morten and see how to work towards real time support.

Should we aim to present something at the rtcweb meeting to the group to 
talk about the coding potential?

In the end it is all about running code.

All the best and see you in Berlin
