Well PP, it clearly has some potential for use in biological warfare, particularly if you don't want a particualr area inhabited for a while:

From the link:
As a biological weapons agent, the Ebola virus is feared for its high case-fatality rate. Because of its rarity, the disease may not be diagnosed corrected at the onset of an outbreak. Reports suggested that the Ebola virus was researched and weaponized by the former Soviet Union's biological weapons program Biopreparat. Dr. Ken Alibek, former the First Deputy Director of Biopreparat, speculated that the Russians had aerosolized the Ebola virus for dissemination as a biological weapon. The Japanese terrorist group Aum Shinrikyo reportedly sent members to Zaire during an outbreak to harvest the virus.
