I have been researching the use of timelocked addresses using OP_CLTV script and have been unable to find any wallets that provide a simple user interface to:

• generate timelocked public address
• set timelock period using blockheight
• spend funds when the timelock period has expired

I believe this is an interesting feature and would be prepared to offer a bounty for a sucessful working example.

Here is a couple of links to give greater detail of how i see this feature could work:

i am also interested to integrate OP_RETURN message functionality as well.
