McAfee buys Safeboot

This is interesting, McAfee has purchased Safeboot for $350 million.
Safeboot seems to be the name I hear most when talking to people at other companies about what FDE products they use. I wonder if ePO will be extended to manage this software in the next few years. That would be pretty cool. I found Safeboot to be rather buggy in my eval. But it seems similar problems occur in any FDE product.
That McAfee would make this purchase shows that they think this will continue to be a big market. One wonders what other companies may be on the market.
