Yeah it's called a voluntary ammortization of debts. The good thing about it is that it does not show up on your credit report as a bankruptcy, and creditors are specifically forbidden from reporting that the account was included in a bankruptcy.
So basically you get the protections of a chapter 13 bankruptcy, without really going bankrupt.
Only problem is that the creditors have to get repaid 100% of their claim amount (unlike a 13 which may let you pay as little as 10%). So if you've got lots of debt, and only 3 years, that can be a very high monthly payment to the 128 trustee.
