I don't believe the myth that 'memory_size' should be the size of the uploaded file. The files are definitely not kept in memory... instead uploaded chunks of 1MB each are stored under /var/tmp and later on rebuild under /tmp before moving to the web/user space.
I'm running a linux-box with only 64MB RAM, setting the memory_limit to 16MB and uploading files of sizes about 100MB is no problem at all! Nevertheless, some users reported a problem at a few 100MB, but that's not confirmed... ;-)
