My kids both have iPod Touches and I'd like to apply some parental controls. I have had a look and I know there are some really limited features on the phone itself, and a variety of filtered browsers. However, none of them are really hitting what I want. The features I am looking for are:

1. Filtered web (as above)
2. Filtered access to Youtube and music
3. Control over how often they are allowed to play games (like 1 hour per day)
4. Whitelist control over who they can skype (or maybe facetime, but I am an android user so can't hook that net.)

Any suggestions?
