Attach file to email sent by triggered rules

I am using triggered rules to notify people of field changes for certain node types. Is there a way to attach a file to these emails sent by triggered rules? The files I am looking to have attached to the email will already be attached to the node using filefield or core attach I can use either, so which ever would be easier to hook in to the rules I'll use.

any thoughts? is there an easy solution that I've overlooked?
