I don't know if this will work for you, but the following javascript will display a pdf on your main page or any page
so you can save the report as a pdf and then display it with this code.
This code works with a hardcoded pdf name,
maybe someone can improve so we can use a variable.
<script language="javascript">
if ((navigator.appName).match(/Explorer/i) != null) {
document.write('<OBJECT CLASSID="clsid:CA8A9780-280D-11CF-A24D-444553540000" WIDTH="100%" HEIGHT="500">');
document.write('<PARAM NAME="SRC" VALUE="test.pdf"/>');
document.write('</OBJECT>');
} else {
document.write('<EMBED src="test.pdf" width="100%" height="500" type="application/pdf">');
document.write('</EMBED>');
}
</script>
