Oooo neat. Doesn't really factor into that particular OpenBSD deployment, but if I ever go back to OpenBSD on my work laptop (which I'd like to do at some point; the previous constraint was that I needed Linux for various tools at work, but I think I can make do with a second laptop and/or using vmm to run virtualized Linux X clients), then this looks like it'd be pretty handy (especially since my work network uses a captive portal now, so I'd want something smart enough to handle that, which sounds exactly like what unwind is supposed to achieve).
