IE6 on XP can actually use TLS, it is just not enabled by default.

But IE8 is readily available on XP so who would use IE6

I think it's probably safe to say that anyone who's using IE6 is either not one who cannot change the defaults (by policy or by skill) or their machine is already malware infested.
