Oh, where I was saying OP_DEPTH, I was referring to a *hypothetical*
opcode; I'd forgotten when I wrote that post that OP_DEPTH is an real
opcode.
These days I'd suggest you use the (upcoming on BTC/live on Viacoin)
OP_CHECKLOCKTIMEVERIFY opcode instead. Pretty simple really:
<current blockheight + 1 year worth of blocks> CHECKLOCKTIMEVERIFY
