I won't lend you anything, but I would be willing to sell you some put options on NASTY shares if you were interested in short exposure to my asset on GLBSE.
Not really, but in any case it's meaningless to buy PUTs from the underlying issuer. If your asset goes bankrupt your PUTs pay how?
You'd be buying them from me, not the asset... I would pay if the asset went bankrupt. I understand your reasoning for trying to borrow shares, but if you want to put your money where your mouth is, I have a very established trading record and would be an honorable issuer of put options for NASTY.
