As many of you probably already know, the US Postal Service is creating a national public-key infrastructure for individuals (I've never heard any mention of Corporate identities, not to say that there won't be any). A few weeks ago the General Services Agency of the US Gov't had an open working session of their Security Infrastructure Program Management Office (SIPMO). At that session they announced a pilot program for electronic filing of federal tax returns, using the USPS infrastructure. The URL in the subject line has not yet been updated to discuss the pilot; right now it is basically an overview of SIPMO. Anyone know more? /r$
