Mac's remote desktop from iPad

Sharing Mac's desktop to an iPad is an extremely handy feature and was for me the determinant factor to buy the latter.

However, is there a way, using native tools (e.g. not VNC/TV/AD and the likes), to initiate this sharing from the iPad, as long as it becomes a trusted device for the Mac?

Since I can have a remote command-line shell to the Mac from the iPad, is there perhaps a command as an alternative way to achieve this?

As it is now, if the connection breaks for any reason, I have to go back to the Mac and perform there the appropriate actions to share its desktop again. It's not too far, but at times it can be inconvenient.
