Why do I think they have little money? In 2007, they lost over $700,000. The company pays it's employees in shares. They have borrowed money from Ed the Convict to the tune of over $1,000,000. All of that says to me, "We are not a profitable company yet."
They certainly should have made money on the deals they've completed, but they also have bills to pay (read: operating costs such as rent, utilities, lease for Access).
Where would the money come from to buyback shares?
