I don't need to seek to a specific uncompressed position--only to seek somewhat randomly with some coarse granularity within the compressed file. I don't mind at all if all I can do is say "uncompess the data starting here, about 700MB into this file."

@John Zwinck: Add your comment to your question as an update. Note that given the variable compression of data (some stuff I compress shrinks by 94% or so - usually, except when it only shrinks by about 50% or so), your estimate of where to start decompressing might be very hit and miss.

Just a note that is complicated by bzip2 block boundaries being within a byte, so it is doable, but there is more bookkeeping required.
