Hi Dave,
Pretty sure there aren't any free things for what you want out there....but it can be done....there are four things that you need....
1)Eye-Fi Pro X2 SD Card
2)Jailbroken iPad
3)App from the Cydia store (you get to this after Jail Breaking iPad) called 'My Wi'
4)App from iTunes called 'Shuttersnitch'
Have a look at this link and watch the video ....it explains it fully

Actually...just found that you don't have to Jail break now....
Look at this link.

i use an eye fi connect x2 with my iPad 3 and it works a treat. Was a bit of a devil to set up but once that was done i havnt had a problem with it.
I didnt bother with the pro version of the card as i just wanted something to simply transfer files over so didnt see the point of the extra costs / options that it gave you.
Failing that you just have to resort to the camera connection kit and dump the images over en masse.
*edit* oh you want to control the camera from the ipad remotely? No idea then, sorry![]()
