So far it's an idea.
I'm not looking to make this a profitable pool, just looking to cover overhead costs of running it. My PPS idea is pretty basic really. If there is enough market for PPS, then I'll setup another server, which will require me to colo another server and then setup pushpool or something of the likes (undecided) and simply just running a PPS with some fee attached to it all.
(Again, this is just an idea at the moment, am awaiting the results of the first pool before I just jump in head first with no idea of outcome.)
