It appears that InfoPath form control can be hosted in a ASPX page, as noted in this article. Currently the RadControls for ASP.NET AJAX do not support InfoPath 2010, although if the standard ASP.NET AJAX controls can be implemented in such scenario, it is quite possible that the RadControls will work as well.
Kind regards,
