I'm a little confused. I've seen the !@#$%^&*ertion repeated that "!@#$%^&*s can't support large zones", but nobody's explained why. Perhaps it's not the easiest piece of software to configure although I could argue it's no harder than subgame, it's just that people are used to subgame). But that's not really a problem for larger zones, just small ones with limited staff and expertise. I think the main reason large zones haven't adopted it is because they've invested a lot of time in their bots and their current serving infrastructure, and it would be too much effort to switch. That's a valid reason, although I should point out that recent releases include a "sgcompat" module that should allow most bots to work with no modification. If I'm wrong about the reason, though, I'd appreciate if someone actually told me, so that perhaps I could help address it.
