I'm estimating the time required to 32h. I suppose that within this time, we will have ready to use implementation (at least in non-clustered version). Most of the tasks should be straight forward to implement, but there may be some obstacles with the database (missing fields, ie. stable subscription id).

This would be initial implementation and future improvements may be required.

The initial implementation is complete. MIX is able to create channel, join, send message, leave, destroy channel. It is possible to check participants and should be possible to retrieve history (however it is not working yet, need to check what is wrong).

This task took a little longer, however it depended on MIX Administration which was implemented while developing MIX, so while this task is finished administration of the channel should work as well.

I think we can consider it in QA as it is deployed and ready.
