How can I get a screenshot of what's on my AppleTV? Preferably Wirelessly. Any apps for that?

Obviously I'm talking about the more recent iOS powered little black box AppleTV, not the original model.
After some quick Googling I found these steps:


Jailbreak
Install aTV Flash (black)
Install nitoTV
Install 'screencapture' (through nitoTV)
SSH in: ssh root@Apple-TV.local (or ssh root@ipaddress, e.g. ssh root@192.168.3.61)
At this point typing in screencapture SHOULD save Screenshot.png to root. If it does not you may need to change ownership on root via: chown mobile:staff ./


Obviously less than ideal, but possible.
