Does anyone have experience with using the iFrame statement in regonline headers and footers.  It seems to work with no problem, but I have heard that frames can create unexpected issues. 

fyi, we are a non-profit, holding events which often fill to capacity, and which are supported by donations of attendees.  Here's what we are putting together:  We want the first page of registration to show in clear graphic form how many have registered vs. the capacity, and how much money has been raised vs. the projected cost of the event. 

We are going to create an offline process that grabs the data every 5 minutes, creates a flash chart, and stores it in a URL.  We'll incorporate that URL into the start page header via iFrame statement. 

e.g.  www.regonline.com/test_chart
