The beta pool could be DDOS'ed off the face of the earth I'm afraid (so have backup pools as I mentioned lol), but when formally released I'll have to make the call on what is feasible, I do want to try and keep the 0% fee but that leaves me with little wiggle room so I'm working on how to get all the bells and whistles and keep that if at all possible. When I start looking at a more formal migration I'll definitely be hitting you up on the offer though! During this "beta" time my concern is to ensure all the optimizations necessary in a somewhat resource constrained environment can handle a somewhat substantial load so that when it comes to migrating to bigger/better servers the infrastructure will scale up nicely to support whatever could be thrown at it and ideally making a p2pool node that rivals some of the larger direct outfits to show that it can be done as p2pool I think has a stigma that it shouldn't be able to handle this much load on a single node, but I think we can do it (tm) lol.
Latency and block times are of a big concern for me at the moment and those need some load testing to see how asics will be able to handle those in p2pool.
