It will however put an insane amount of load on whatever server it is served from.
Supporting buttons was the first thing that drove reddit to getting a CDN. We also made it cache the score for a few minutes for non-logged-in users, which helped alleviate a lot of load.
Great idea, but this makes me scared.

What it would do is give the large-trafficked sites a significant advantage since they can leverage their own traffic. You could see that on Digg years ago, the front page was largely devoted to a selection of sites - Engadget, TechCrunch, Huffington Post, Ars etc.

Points/upvotes on articles should not be allocated to the user who submits that article (unless perhaps, it's an "Ask HN" submission); points/upvotes should be allocated to users only on the comments they make. I agree with Jacques that this would improve the level of discourse on HN and also remove down-vote capability from those who have not earned it through quality comments.
There are a number of ways to make this change: (i) points received from article submissions could be retroactively eliminated from a users score (ii) or separated out from points received on comments--possibly an interesting new data point, (iii) or the points could simply be associated with the root URL of the content source and then displayed on a new page as a list of "Top Ranked Content Sources"--this might also encourage less duplicates and an effort to find the best source before submitting a story... (iv) or maybe this is all just wishful thinking?
edit: here is the associated HN discussion for that article: http://news.ycombinator.com/item?id=2386443
In any case, a button that displays the HN points (without upvote feature) for a given content is useful. The question is whether to include the upvote function in it or not.
update: there already is a bookmarklet and a Chrome extension for it so this is only an addition to the list in this regard
pg's raised these issues, and I must say I'd like to see some discussion about them.
(these are just suggestions I have no idea how the current algorithm works)
This hidden valuation will probably also have to exist for user karma. Curiously, this is what is claimed in many esoteric schools concerning karma itself. The mechanisms are deliberately hidden "by the gods" so that one does good for the sake of good and not with any intent of gaming the system.
Could beginning more minds and data beget innovation?
Wherein here we innovate without sin, I do not understand why enabling new power is.
