I don't think they are quite the same.  The TCP time stamp is
an attribute of the destination host, it doesn't vary depending
on which route you take to reach the host.  The MTU on the other
hand is an attribute of the route that reaches the host.

BTW, it appears that the inetpeer cache doesn't take namespaces
into account.  This means that information could potentially leak
from one namespace into another.  I'm not sure whether that's a
big deal or not but it's something for the namespaces folks to
consider.

Cheers,
