How fast must new obfuscated bridges be created to replace old ones that
have been discovered? What's the mean lifetime of an obfuscated bridge?

If obfuscated bridges don't last very long, it's very likely that ef2k's
ISP will quickly determine that he's using Tor, even if it can't
consistently block Tor use.

If ef2k were using a VPN service, on the other hand, his ISP would need
to gain cooperation of his VPN provider, or snoop its exit traffic. And
he could choose VPN providers prudently to make either harder for his
ISP to accomplish. Or he could nest multiple VPNs.

He could also use both VPNs and obfuscated bridges, if hiding Tor use
really matters.
