Checked three file sharing solutions:
All the three offer a free service of upload of files up to 100MB. We are evaluating yousendit. I find the following features useful for us. Business Plus Acct- USD 29.95 per user.
– Allows secure file upload , receipt acknowledgement and tracking of the downloads
– Can brand the site in a limited way
– Has a feature for drop box. This URL can be sent to our customers to directly upload files using an email metaphor
– Can also embed this URL into the website so that clients can upload files directly to the drop box
