A group called the "Holics Project" have again, according to various reliable resources, successfully released a working "crack" that disables Plus! Digital Media Edition's WPA (Windows Product Activation) module. The group responsible for cracking Office 11 seem to have done it again.
Microsoft's first test of a home user product with activation has been broken. A reliable source has informed me that the "crack" works as-long as you don't have DME installed and any previous Plus! packs installed. The crack itself consists of just a registry file which is run before "Activation".
At the moment there has been no comment or response from Microsoft, although I expect a "patch" will likely be made available to render the crack useless and fix any slight bugs in the program itself. Until then it appears its crackers one ;), Microsoft nill.
