The application I'm developing can't seek past 2GB in a file because the seek() library function takes a signed 4-byte integer. I think this is a common problem. I can read larger files (so a >4GB JPEG image isn't a problem for instance), but due to the TIFF structure, you have to be able to seek to an arbitrary point in the file. So the limit is 2GB. Placing IFD0 first would help, but any data starting after the 2GB point still couldn't be read.
