If the iframe is from a different domain, but you have control over the content, you can communicate between the two in a couple different ways. The simplest is to "talk" through key/value pairs in the URL of the iFrame, since both the parent and the iFrame have access to that.

A more complicated approach is to use iFrame proxy's, which is described really well here: http://www.julienlecomte.net/blog/2007/11/31/ which uses Yahoo Pipes to send messages back and forth quite nicely.
