"In a corporate environment, I don't want to wait around for 3.5-4 hours before my data even becomes available for restore in a disaster recovery situation."
I am guessing you work in a company with a good IT department then, I am guessing this is not the average. Many companies I have worked for 4 hours would be a miracle with a 1-3 day operation minimum.
And don't forget that the X00MB type size limits many IT departments puts everywhere it not because getting a TB hard drive is cheap, but because all of the extra backups add to the cost of each new MB. Having another extremely cheap way they could backup large amounts of data (encrypted?) would help to reduce the cost of each extra GB.
