[Flac] Archiving CDs w/ Flac on Linux (and subsequent re-encoding)

[Eric Sandeen]

This must be possible; not sure how to do it yet.  :)

After facing the thought of going through my cd collection for a 3rd 
time for re-encoding, it occurred to me that I should just flac the 
whole CD and add a cue sheet, and then back up to DVDs.  That way -next- 
time I need to re-encode to any format, I can handle ~1/20th the discs, 
compared to my whole cd collection.  :)

Wondering if anyone has a good way to do this; my primary questions are:

1) how to generate a cue sheet to store in the flac file (on linux?)
    I've seen cddb2cue, is this a decent way?  or cdrdao can generate
    a toc file, then convert that to a cue sheet....

2) after I've got a full-CD flac file with a cue sheet and seek points,
    how to re-encode this track-by-track, to ogg or mp3?  I don't see
    any command-line flac decoder that can say "play from seek point
    3 to seek point 4"... looks like the flac executable itself can only
    seek based on nr of samples, or hh:mm:ss?

3) Finally, can vorbis comments in a flac file store binary data, such
    as album art?

Thanks for any info & pointers (and I hope this reaches a person or two, 
what with the recent mailing list hosting change....)
