This stock's price has been all over the map from a low of 6-cents a share to about 45-cents a share during its most optimistic days, then about 21 cents a share a few weeks ago before some big announcements about getting clearance to use Union Pacific's tracks... and now the stock is back down to 10-cents a share which is where it was a year ago.

Hurting investor confidence? Perhaps that service won't start till the end of 2013. That's a long time to wait -- in this Internet-fast world -- for revenue to start coming in.

But at a dime a share how much of a gamble would it be?
