You're probably right re: amended registration. But I do have a rough time believing those shares were sold on the open market (like they need the cash). Perhaps a swap of shares for warrants with S&L (assuming S&L had lowered their share count to accomodate).
I'm under the impression that SSDI is a new entity created for the JV. I do find this a little odd, in that they said they were going to keep the "Holocom" name. But Holocom is probably trademarked, and they own the trademark I'd think, so they could use that name on the product.
I KNOW nuttin'!
