Has anyone looked into the flattened BMessage format yet? I wrote a BMessage
implementation, but flattening and unflattening is still not compatible.
This is what I found out for a message like the one posted at

Some of the header information and the count for the entry_hdr structs is
still missing. Any ideas?
