Re: upload limit and disk space alotted
The Magento Community Edition zip archive (the largest version of the download) is only 25MB. There's no law saying you need to upload the app as an archive -- uploaded as expanded files (via FTP if you want to batch it), you can get by easily with a file size limit of 1MB (much bigger than any file in the archive, and it ought to be bigger than any product files as well). You don't need a 256MB file size limit for Magento.
