Despite that, this kind of feedback is great. PCs need a wider array of 'generic output' devices which can be tailored to people's needs.
if you want lights (LEDs actualy), check out http://www.epanorama.net/circuits/parallel_output. html
I build one myself for the sake of trying it. It's really easy and really cheap. I don't really have any use for it, but it's basically one or more LEDs at the end of a parallel port cable. programming it is also pretty easy.
could easily be used for that kind of stuff...
This is not really how it is supposed to work. The cool thing about steganography is, that you might not even know, that a picture has a message encrypted in it, because the data is there any way.
since XML is clear text, one could easily see any encrypted text in it, as it is NOT clear text...
of course, you could put tags with encrypted text in it that wouldnt get displayed, and as probably only few people would bother reading the source of a svg file, only few people would find out.
but if you want to, you can have the pure ciphertext and run cryptographic attacks on it.
So it is not really anything like steganography, you could as well hide your encrypted text in the comments of a pdf file or whatever...

There goes some of Bill's money...
that' AND, not XOR XOR is 0 if input bits are equal, 1 otherwise...
