Does anybody have any thoughts on this opening? I cannot find it in either BruGo or Kogo, and I am unsure how to play against it.

It seems Black has crawled one time too often, but his position is solid and there is an opening at a.
Yes, Black has crawled and gotten a low posture. His position is not all that solid, and "a" is not that good for him.
Tenuki is possible for White, and if White had only two stones in the corner, it would be easy. Three stones is more difficult to leave as is.

Your

wall needs eye potential if you are not going to treat it as kikashi.
provides that. Black cannot push and cut because of the net. If Black makes another local play to enforce that (like
), you can consider sacrificing the wall.
is not indicated. Later White might play at "a" to bolster the group.

However, White's influence does not look all that impressive, while Black seems to have acquired a fairly hefty profit.
Am I missing something? Is my thinking all wrong on this?
Thanks!
Yes, you are. Black only seems to have made a profit here. In fact, he has made a loss. You have to remember to consider the influence of the original 3-3 stone. With three moves Black has gained around 6 points. The influence of White's wall is easily worth more than that on an empty board, even considering its weakness. If you can make the knight's move with sente, so much the better.
Take a look at some ancient games, like in early 19th century Japan. Play was more territorial than today, but players were content to make walls that not only did not seem impressive, but did not seem to do much throughout the game. Those games are well worth the study.
