I figured it would be interesting at the least to you and others. Also, the form (as Chex has pointed out also) that there are those who are exempt from FinCEN transaction reports. Psycopathic, envious or shady tellers have been known to file nasty FinCEN reports out of spite--with the exemption certificate in place I suspect tellers and bank staff would be open to sever criminal and civil liability should they do such things in face of an exemption. Conceivably a substitute certificate could be executed by an accountholder or the like and served on the bank through Treasury (i.e. copy to the bank w/ certificate of service and original to Treasury --by fax or by mail).
P.S. Something tells me that, where applicable, a "Certificate of Exemption In Lieu of FinCEN Form 110" might go well with a W8 or the like.
