Doing jQuery on a remote page.

Doing jQuery on a remote page.

I am developing a database program that need to insert an address into a text box on a remote page. Basically the program is being developed for the ultimate in lazy people that do not even want to copy paste the address into the text box it should already be there when the page loads. I have been contemplating using frames although I'm not sure that will be possible. Also I have been researching options that will include the remote page inside my page without the use of frames although I'm not sure this will be possible either. I have already explained to my client that I may not be able to accomplish this but he keeps stressing the use of this feature. Is there anything I can do to code something like this?
