Question for Apple:
Why have you not developed something like this for all faithful users of your meMobile? I would strongly suggest that you buy out this software and make it available as the part of meMobile service. Where is your innovation spirit? At the same time I would like to see that all these different file formats to project from iPhone/iPod.

If you look on the home page in the lower right there's a link to extensive security policy document. Soonr has all bases covered - physical security, logical security, technical security, and anti-hacking. The service is hosted in a SAS70 datacenter with over 99.9% uptime. The architecture of the service is multi-tiered with user account and file information in separate databases and servers (stealing one server would be useless). All transmission are encrypted from the desktop to the client. Finally, it is authenticated (Verisign) and tested daily for attacks (Hackersafe).

I don't know how much more you can ask for! Soonr meets all the modern expectations of a secure service. Investors include Cisco and Intel. Each of these large enterprises know a thing or two about network security.

BTW: I am one of the Soonr folks. I hope this post answered your question.
