Question: Safe Harbor Money Market Funds

 I have a significant portion of my 401K retirement savings in the account's sweep account, SSMXX, SSGA Money Market Fund.  As of yesterday, 10/01, ING/Citistreet have not yet decided to participate in the Treasury Dept's plan to guarantee up to 50 billion for the next year for retail money fund investors.  I understand that I can reduce risk even further by limiting myself to funds that invest in Treasury securities only, from companies with deep pockets and reputations to protect.  I am overwhelmingly interested in capital preservation during a financial crisis such as the one we are experiencing, and the return on my investments during the crisis is of little importance to me until after "the dust settles" somewhere down the road.  1.  Should I wait until the October 8th deadline to see if ING/Citistreet enrolls in the Treasury Dept's plan, or bail out of SSMXX now?  2.  If I should bail out of SSMXX now or potentially later, would such funds as CPFXX, RUAXX, UTAXX, DIRXX, VPIXX, RJTXX, or VHPXX fit the bill, or would others do so better?
