comment Automatically check student answers in tests
I have a prototype for this. It uses a combination of mathematica and a web server. I'll try to find the time to post my detailed setup.

@Murta The originals were taken offline. I am traveling right now, but as soon as I get back I'll look into fixing the .torrent file and let you know.

Besides the author, I am using it. I don't know who else, but it works beautifully.

comment How to pop out of a subsection in a notebook
I understand what you need. You may want to do some tests with Cell -> Grouping -> Manual Grouping and then manually grouping the desired cells. Also you could create "Item" cells instead of "Subsection" cells and "ItemParagraph" cells for the text inside each item.

comment How to asynchronously download 100000 urls in an efficient way
Before URLSaveAsynchronous I used Mathematica to monitor the performance of a ruby download script and change the number of threads to maximize performance. Now it should be possible to do all in Mathematica and take advantage of the advanced parser (patterns for XML) not found in other languages. I wish I had the time to work on this now.
