I know that the Johnny Cash estate just about wiped out all forms of infringement on eBay. No matter if it's big or small, if they catch wind of something, they go after it bent of getting it removed.
I've said this before and I'll say it again, Mark Knopfler's policy in regards to bootlegs is the best show of fan appreciation. He has no problem with fans coming to his shows and recording or filming them, just so they don't ask to get a live feed because that will never happen. He said he likes to see all the little red lights staring up at him while playing and he knows that anybody that would record something already has everything officially released anyway.
Perhaps Lightfoot can do something like this.

I've purchased 2 concerts, and one of them I purchased a 2nd time because I reached the maximum amount of burns. The Nashville show blows away, and I mean blows off the face of the map any live recording I've ever bought as an official release. Eventhough it's a digital download, it's very, very clean and crisp. Burning at 1x (if your burner will not burn @ 1x, then 4x max) will preserve the quality.
