This is really great news, an issue i've been agitating about for a while now. The current system "requires" companies to pay in $2000+ to get a legit vendor id block of 65536 product ids, even if only a handful of product ids are needed. Some chip vendors help out (I think you can get msp430 IDs for free if you ask nicely), but there hasn't been a systematic way for small (for-profit or non-profit) projects to get a legit ID.
They are also making ethernet MAC addresses available.
I hope in the future these blocks can be turned over to a group like the Open Hardware Association to be maintained in the long run. It's a sham and a shame that these industry groups are always structured around setting up these artificial financial barriers to entry; surely reasonable administrative overhead costs ($120k a year?) could be covered by donations from larger companies or a government/foundation grant. See also recent efforts to publish expensive copyrighted standards on the (ethical) grounds that they are effectively a subset of US federal law.
