Greetings. An IT professional friend of mine has founded a company to take on Dropbox. Basically, all his IT professional friends hated Dropbox because it wasn't secure, but the secure alternatives were not easy to use or price accessible to IT professionals at small/medium businesses. He's had over a year of development, and now has dozens of active deployments, so it's time to get the word out. Feel free to check out the website and give it a try. It's priced very low for now.

(Yes, I'm interested in seeing him succeed, but I also think it's a product that fills an unmet need, and so could be truly beneficial to this community of which I consider myself an albeit small part).
