Oh come on. Like they're not going to get caught stuffing an entire T1 with LSRR packets. Face it. You're grabbing at straws.
Can I grab at one too? I'd love to see LSRR (and SSRR) dead because it slows down single-path forwarding considerably, and complicates fast-path/slow-path systems in gross ways for what I believe is minimal added utility. Some folks may have run across more uses for one or the other that involve more than 'traceroute -g' or 'telnet @foo:bar', both of some utility, I suppose, but one is easily replaced with application-level proxying, and the other is just weird. Or vice-versa. Of course, I don't have a religious feeling about this, since I try to persuade my vendor(s) to supply routers which can handle tiny Christmas-tree packets (those that are fully decorated with options) at line speed without loss. Then again, I work for a company with deep pockets that can afford what it takes to buy per-packet time budgets that can satisfy that kind of design criterion...
