The 300k chunk size limitation comes up regularly, and Adobe seems to think the limitation has to do with Sony Readers. True?

Well sort of true. They actually say the limit is for portable devices and Sony is certainly one of those. The reader extracts the xhtml file from the container in some fashion and loads it into memory. This is so pagination can be accomplished on the file. I believe the real limit is likely the 100K or so compressed size of the file since it is likely they use it compressed. The Sony 505 has 256K of memory I believe but leaves about 190K for the user. They may be sneaking a bit of user memory for this task or using cache on a memory device but I am not sure. In any event the Sony will choke if the file is too big.
