With respect to the RO issue, if you are a corporation with only one RO you're dead in the water.  [And its not like you can really make up another RO for a corporation.]  IRS is well aware of the problem and (per them) they have been aware of the problem since last spring.

Can't make that one up!

Guess TCC and IRIS is off the list.....don't expect it to actually be functional for a few more years anyway.
