Is it planed to have a feature that allows to add a list of files in a space. Actually, it is only possible to add one file at a time via the web interface.
I don't know, if your posting is still open, but one answer to your problem is FTP. There you can adress your alfresco server via port 21 and bulk load more than one file. You may use your Alfresco accounts for ftp as well. This works very well.
