discussion: script to notify you when your land sells

In reponse to Diamondback Deckard's question in SL answers about land management tools, I created this script :

integer ctime = 10;

default
{
    state_entry()
    {
        llSay(0, "Online. Will check every "+(string)ctime+" seconds. If land owner is NOT the same as object owner, will message object owner with location and 'your land sold' message, and self delete.");
        llSetTimerEvent((float)ctime);
    }

    timer() {
        if (llGetLandOwnerAt(llGetPos()) == llGetOwner())  {
            // object owner matches land owner
        } else {
            // object owner does NOT match land owner!
            llInstantMessage(llGetOwner(),"Your land at "+(string)llGetRegionName()+":"+(string)llGetPos()+" has been sold. The new buyer may be : "+llKey2Name(llGetLandOwnerAt(llGetPos()))+" (if this fails, a group now has it).");
            llDie();
        }
        
    }
}

It's very simple : it simply sends you an IM when your land is sold to someone else, then deletes itself. I've NOT tested it AT ALL, so I make no assurances AT ALL that it will work. It's intended to be more of an idea than anything else - if it works, consider that a bonus
