I like Impress or Moxie.
MOx to me conveys nothing at all: I look at it and I'm not even sure how to say it. The capitalization is funky. And it doesn't feel warm and fuzzy. Missouri X?
Intrasect I've ran by a couple of non-geeks and they both wrinkled their noses and asked if I was going to start with the techno babble. Not sure that was a good sign.
In general, I'd advocate things that are real words or sounds like they could be a real word, doesn't have mysterious elements like "X" or "I" or "E" that don't actually have any meaning at all, and that has a nice rhthym when you say it.

With the possible exception of Coca-cola, not a single one of those names have anything to do with what their product is. Yet they stick because they are short, memorable, you don't have to guess as to how to spell/say them, and they have a nice sound when you do say them.
Just my two cents.
