The CPSC has opened a comment period for component testing (as opposed to testing each variation of a final product).
For details, see the pdf here: http://www.cpsc.gov/about/cpsia/componentpartscomments.pdf
On the surface, this seems like a much better solution for small, homemade product designers. But, it isn’t as simple as it seems. Most importantly, it might allow for a central database (vendor by vendor at least) of GCC/test data that makers of childrens products could use for references and compliance.
Time will tell as the implementation is everything.
