Several products have popped up during the last year or so that try to use peer-to-peer technology to make it easier for users to send very large files. Sage Analytics Technologies MagicVortex is a more usable and effective tool for this than most others, in part because it isnt a true P2P product.
To use MagicVortex, I signed up for the service (a free 30-day trial is available) and downloaded the Windows-based client software. I then chose a large file to send and entered the recipients e-mail address. The MagicVortex program then slowly sent the file up to a central server array.
Once the upload was finished, the recipient received an e-mail message that contained a URL. At this address, the recipient could download the file through his browser in an SSL connection.
The browser download worked very well for files in the tens of megabytes, but those receiving very large files may want to use the MagicVortex client for the download.
I found MagicVortex to be a simple but effective tool for sending large files. The client upload is secure and reliable, and the recipient doesnt need to do any upfront work to receive the file.
MagicVortexs pricing starts at $9.95 per month. The program is at www.magicvortex.com.
