There is also the consistent references to threes and trinities. Owing to Bakker's Christian upbringing no doubt, but I wonder if any are really more than window-dressing?
On the Finnagan's Wake point, I believe it goes back to the opening, about ears and hearing, war and conflict, as that passage seems to speak of the juxtaposition of Babel and Lebab, basically language and heart, a palindrome as well, then set against the idea of war (but Joyce seems to mean it differently as, He Was, but maybe so does Bakker). In this way, perhaps (I think it was Locke who first did, maybe others) pointing out that Earwa is an anagram for Aware does have meaning.
Also interesting in looking at this, was how Yatwer is a two letter substitution for Yahweh, but that is neither here nor there in probability.
EDIT: Also, IIRC, there is a mention of Shambhalla in relation to WiFi as well, which is actually from the modern Doctor Strange movie (apparently, I haven't actually seen it yet), where "shamballa" is the password.
