PPIP= Public Private Investment Program
There are similarities between the PPIP and the Resolution Trust Corp which helped resolve the Savings and Loan crisis.
The article points to recent (as in, last two weeks) improvements in the market for commercial mortgage bonds and mortgage backed securities, suggesting that investors are responding appropriately to the PPIP:

"Top-rated commercial-mortgage bonds rose 5.6 percent since March 20 to about 79 cents on the dollar on average, according to Merrill Lynch & Co. indexes. The most-senior class of benchmark 2005 securities backed by fixed-rate Alt-A home loans, or those ranked between prime and subprime, increased about 12 percent to 54 cents as of March 31, according to Deutsche Bank AG."
