I've been playing a little bit with the wordpress importer. I made
some changes, it uses plupload to upload big files. The backup file is
also read and imported progressively. I only made some tests with
dummy backup files (38MB and 185 MB) on an old laptop. My php
memory_limit = 32M
upload_max_filesize = 10M
post_max_size = 20M

Yes, it was slow, but the importer didn't die.

If you are interested, you can grab the code from
There are many things that may be improved.
