SURE - cash is the life blood of any business and I could name many other companies that have bought other businesses at extremely high prices ( with the benefit of hindsight)and are still not moving, simply because the fish arn't biting in this current climate.
The question has to be 1) When will the barriers to entry drop sufficiently to allow market penetration?
2)Will this happen before the cash runs out?
3)Can the management of this company run the business better than BII and achieve profitable growth?
