While I do like the whole WRT54GL thing, you do appear to be answering a different question to the one that was asked.

I tend to use Mikogo - has worked fairly well for me so far.

And it's free and easy to use.

From page three:

"Q: AMD was able to open source and/or document a lot by separating out the parts they couldn't legally disclose. Similar problems have been cited as preventing NVIDIA from open sourcing their driver (licensed 3rd parts code, etc) or documentation. Could nVidia use the same strategy?"

"... While at some point it may be possible to release some of this information in pubic form ..."

Ever the child... I must admit it made me snigger...

Completely different issue there though, that one is due to the regular array of windmills acting like a diffraction grating and proucing multiple radar images of a given object. (Or so I've heard anyway).
