Q: How to remote access iMac from ipad

Yes. I particularly like Teamviewer

but there are many others.

Apple Remote Desktop however only works within the same Network, and not over the internet.

This is incorrect. I use ARD to log into work, and home, machines over the internet all the time.

It is less than accurate yes. However for ARD to work over the internet several settings need to be applied on the remote router so ARD requests are forwarded to the correct machine,  which may or may not be possible. As well as knowing the public IP addresses of the remote network.

It would also be limited to 1 computer in the remote network, as you can only port forward to a single computer. 

Its quite more involved than simply installing Teamviewer, and logging in, or remembering a number and password.  No extra route settings required.
