llGetOwner() in different sim

it appears that llKey2Name(llGetOwner()) doesn't work on an object (created by the owner) if the owner's in a different sim or offline!

is there another way to get the owner of an object, when the owner is in a different sim than the object?

--

testing just a simple script out. having some sandbox guy click the object while i'm gone. when i'm present, the object blurts out my name. when i'm gone, the object doesn't say anything.

default
{
    state_entry()
    {
        llSay(0, "initializedd!");
    }

    touch_start(integer total_number)
    {
        llSay(0,llKey2Name(llGetOwner()));
    }
}

This behaviour is consistent with: http://www.lslwiki.com/lslwiki/wakka.php?wakka=llKey2Name

The answer is to preserve the Owner's name in the state_entry Event and when a change of owner is detected in the change Event:

string oName;

default
{
    state_entry()
    {
        oName = llKey2Name(llGetOwner());
        llSay(0, "initializedd!");
    }

    touch_start(integer total_number)
    {
        llSay(0, oName);
    }

    changed(integer change)
    {
        if(change & CHANGED_OWNER)
        {
            oName = llKey2Name(llGetOwner());
        }

    }
}

This is probably more efficient too.
