1. I haven't run into user-agent blocking where I live, maybe it is a regional thing. I have the user-agent on Opera mobile set to use the desktop version without issues. Additionally a few weeks ago my power was out for a couple days and my phone became my primary home internet connection, no browser on 1 windows and 2 linux PCs was blocked.
2. I doubt they would be able to see the TTL. The TTL of the ssh packet would be unchanged, and the TTL of the tunneled packet would be encrypted.
Our algorithm works by adding a high-frequency pattern to the image with an amplitude carefully selected to cause maximum quantization error on recompression at a chosen target JPEG quality factor.
The key here is JPEG quality factor. This only works on a specific quality factor. Just pick a different one. I just tried it using their example image. At some quality factors you can see somthing funny going on (spots on image). But, at any factor you would use to actually compress a photo (above 90) the image looks fine.
This could work for the bandwith-saving proxy mentioned in the article since they will have low quality factors. But what would be the point then? Mangling images when viewed on a cellphone?

Um..... RMS, Linus Torvalds, Guido van Rossum, Larry Wall
The Notepad Bug still exists in vista.
Here's how to do it:
Open up Notepad, of course. Turn on 'word wrap'. Start typing. Enter some huge lines of text, ones that wrap several times. Save the document. Did you notice that the cursor position changed? Start typing again. Things get even more weird from there. Lines will no longer wrap properly. The text may get scrambled. Problems may occur. Your document may even get corrupted.
For every complex problem, there is a solution that is simple, neat, and wrong. -- H. L. Mencken
