Plugin for jQuery (tooltips)?

Question

JavaScript

We need a plugin that will display a floating block anchored to the cursor when hovering over the desired element.

Requirements:
1. Binding to elements by selector.
2. Customizable spawn delay.
3. Taking into account the borders of the window (the block should adjust its position, and not crawl out of the edges).
4. Call the callback function when it appears to get the contents of the block.
5. Possibility of redrawing the visible block (with adjustment of the position taking into account the new dimensions).

Preferably, the following should be missing:
1. Standard frilly design
2. Standard elements (for example, tooltip title)
3. Non-switchable animation

Have a look at Tooltips in Bootstrap twitter.github.com/bootstrap/javascript.html#tooltips (although you will need not only Jquery, but Bootstrap connection as well).
