Uploading user created levels from webplayer

I'm trying to create a function that allows users to design and upload levels for my WebPLayer game. Initially my plan was to write the name of the objects, transforms etc. into a text file and use FtpWebRequest to upload it to my server however unity does not allow access to Systems.Net.Webrequests.

I am wondering if someone could point me in the right direction. I saw this post but this seems tedious for storing and allowing me to access their level designs (at the moment, I would like to personally check each level to ensure its functionality).

Any help you be much appreciated!

Thanks in advance, Noah
