This software allows you to access files on your pc by using a software install on your Pc and their Avvenu Access & Share online account.

The features are:

Share a large file or folder
Grab the documents you need
View and share your photos
Listen to your music on the go? ( got to test it )

From Avvenu:

Avvenu gives you a direct route to your stuff on your computer, whether it’s your iTunes music collection, your photos, or your documents. Plus, you can share any file on your computer, with anyone you choose. Listen to your iTunes music collection–View your photos–Grab the documents you forgot–from anywhere even when your computer is turned off. It’s a two-minute set-up, and it’s instant gratification.

Free File Sharing Service
With Wikisend it`s simple and free. Upload and download lots of files, big files, small files, data files, media files, archives or backups – any files. Share files with your friends using E-mail, MySpace page, your blog, forums and so on.

In my view an interesting concept but I don’t like the 100 MBytes limitation, also the no need to register makes it easy to spread viruses & co.

I like the options of defining the lifetime of the file ( 1-90 days ) and being able to protect the file with a set password. So based on only these two features I don’t see what the revenue model will be other than the obvious – more storage for mo money.
