I would be interested in buying 1 CALL contract (covering 100 BTC) at DEC 31 2014 expiry with strike price $500.
Accepting offers.

And info on which platform we could reliably actualize this deal. I would imagine interested party would have to transfer his 100 btc to mutually agreed upon escrow person for the duration of the option.
I would like this to be US style option - meaning i can execute it anytime before expiry date.
There is icbit.se
The problems with bitcoin options
* Liquidity.
* Difficulty in pricing.
* You need a trusted third party ("counterparty"). In the bitcoin world - where exchanges go under regularly - I believe that can be pretty hard to find.
* Regulations.
I think mainly though it's a problem with liquidity. There is icbit.se already, but most of the derivatives there are thinly traded. Once the spread gets beyond a certain point, it doesn't really work..
PS.
I dont see "nobody would write it" as a valid reason why , for example, a CALL option does not exist. I'm sure *somebody* would, it just would depend on the price.
