You make a fool of yourself within one sentence. You say that you 
neither know what it is,
nor do you want to know, but you really dare to judge the complexity (or 
lack thereof) which
it adds.......if you had looked at my audio reading classes, you would 
have noticed that
resolving the laces (= hide their existence for something using that 
class) causes a neglectible
amount of extra code, compared to the size of the AVI or matroska 
parsers, or even writers.

For CFR, you can leave out some time stamps and then accurately guess 
them back. For
VFR, you can't. So you can only seek on Block accuracy for VFR, but 
frame accuracy
for CFR. Thus, if you want to maintain frame accuracy for seeking in 
VFR, you need one
block = one frame = no lacing. If you don't need frame accuracy on 
seeking, you can
surely lace VFR.

That's why avi-mux gui does not lace vorbis audio by default...ups, 
again this bad word
you don't want to know nothing about :p

Everything shows up nicely here. I don't even use UTF-8 for those who 
still use
primitive OSes.
