You can create as many simple revocable trusts as you'd like using a Nolo offering and a visit to your bank for notarization.
I've heard TD will sometimes complain about a trust with your SSN as its TIN, but I've had no problems. After all, it is still a separate entity and that is the technical requirement.
Managing your own records and dealing with TD's horrible login process are the main hoops to creating multiple accounts. I appreciate the GreaseMonkey snippets for fixing their password input, that are listed elsewhere in this thread. But what would be really fantastic is if OP published their code for programmatically interacting with Treasury Direct.
