I'm looking at setting up some other region pools for hashbag.cc, so I'll add SEA to the list and I'll make a post in here if it eventuates.
At a glance, Singapore looks like a reasonable place for cryptocurrency operations and is reasonably central to the SEA region.
Sydney is another place that we could potentially host a pool, but I need to check that I'm not going to be stepping on any toes regarding the creation of cryptocurrency in the locations I'm looking at.
