Berg111,
Thanks for your post. It's not easy to evaluate the amount of short interest, especially on an OTC stock. Remember, everything is being done illegally, so these people take great care about trying to hide their tracks. I have heard estimates of the total amount of short interest between 30 million and 150 million (in one case, even 200 million).
If it ever happens that a high proportion of shorts try to cover at the same time, you can imagine the consequences!
BTW, Kenco is a notorious basher of SunnComm, and has a lively interest in Macrovision. If you look up a few of his/her past posts on IH and on RB, you will see what I mean.
Best regards,
