问题
I've been working with selection/range objects, and because to the incredible amount of inconsistencies between browsers for specific selection/range stuff (even more than the DOM) I was wondering if there was a framework that would help me get through them.

Take a look at IERange:
IERange is a feature-complete implementation of W3C DOM Ranges for Internet Explorer, allowing users to write one cross-browser version of their range manipulation code.
Supports Range APIs:
document.createRange()startContainer,startOffset,endContainer,endOffset,commonAncestorContainer,collapsedsetStart(),setEnd(),setStartBefore(),setStartAfter(),setEndBefore(),setEndAfter(),selectNode(),selectNodeContents(),collapse()insertNode(),surroundContents()extractContents(),cloneContents(),deleteContents()compareBoundaryPoints(),cloneRange(),createContextualFragment(),toString()
Supports Selection APIs:
- Range support (Webkit-style)
window.getSelection()addRange(),removeAllRanges(),getRangeAt(),toString()

I've written a new range/selection library called Rangy that is similar in concept to IERange but goes quite a lot further. The core is pretty much complete and currently available to download. I'm currently bugfixing and documenting it and it should be only be a few weeks before a full release.
UPDATE 31 August 2011
Rangy is now stable and at version 1.2 (downloads page).
