info packets could be used for many things
1. chapters
2. scene description, like storing all the start/stop times where gandalf 
appears or the start/stop time of commercials, that would be quite nice for 
seeking
3. storing other data, like gps coordnates (that way u know where the spot 
from the documentary is exactly, so u could easily visit it for example)
4. storing the (x,y) coordinates of an unimportant rectangle for subtitles for 
the current scene
5. storing interlaced/pogressive/telecine flags
6. storing object descriptions, like the names+info+coordinates of vissible 
plants, animals and the like for educational material

but the the most important thing is what we dont know yet, if nut really 
spreads and is used by alot of people, nut will be used for alot of things we 
didnt predict, and alot of what u call braindamaged now will turn out to be 
the only possible solution to some problems

ok, (language, disposition, audio-gain in the stream header)

and iam very strongly against putting limits in a format because we fail to 
find a good example where its usefull
as long as something doesnt add any comlexity and adds possibilities it should 
be supported, possible abuse or braindamaged are IMHO weak arguments, 
everything can be abused and everything is braindamaged from someones point 
of view
