@heapwolf All of those can be solved in various ways. Currently, with pre-alpha code and zero investment, you can set up a small web site that is maintenance free in under a minute with zero technical knowledge for less than €10/month. All of those numbers can be improved in the future with investment from the commons but anything beyond that is premature optimisation at the moment.
Regarding sockets (congrats on shipping, btw): how do you handle offline messages if not without always on nodes?
