The bolded section is the way in which memory operates and which could be represented by changes to DNA...?
The relevant "velocities" in this case could be seen a bit more clearly as the general ratio of motions/changes that satisfy these versus those that don't. If there is a reason that faster than light speed velocities is valuable (in itself it has no determinable/controllable value if the destination or states/positions passed through cannot be determined to have such value), then we'll pursue it (and there's actually no physical law that denies it's possible but instead that if we use light to navigate by and conventional manners of observing and learning of space, then rather much by definition we'd be travelling through such conventional forms of space). In order to move in a different manner with any utility, those components that allow for such faster than light motions to occur would need to be used - for example, one component needed would be a manner to move without navigating using information conveyed via. light would be needed (so in a sense, the motion would not be through a conventional light speed space). Another component that would appear helpful would appear to be intuition or faith as requiring events repeat multiple times before a landmark is declared would lead to a space with lots of repetitions

So in some ways - just going, without stopping to know everything along the path can make for a bit faster velocity to the trip - of course such motions would not be "provable" in the typical sense of empirically measured motion through a space.
Anyway, it's just interesting to see that there's actually some solid logic and information theory behind things that could normally appear as myth/pseudo science etc. and there can be real reasons why some forms of phenomenon cannot be proven to exist and can appear to only be experienceable or subjective.
It's also interesting to see correlations between different classes of thought processes and some of the characteristics of the "spaces" these perceive are.
I guess the main point is that I believe we
already "travel" at the speed of knowledge/experience etc. and this is not a specific velocity in space. The manner in which we figuratively "navigate" determines that velocity ...
different ways of navigating .... different velocities 
What's the most important metric for velocity?
