Figure out how to build a cross 2.1 / 3 test suite that doesn't require hosting multiple copies on w3.org or has some other way of letting us identify common test results in the results system?
Tooling Issues
Changes to the build system should make its parts easier to use for other purposes, and to generally improve its usefulness to testers and test writers.
incremental builds
live copy of test suite
break-downable list of all filenames
search on test metadata
sync support files (and reftest supports)
Minor issues
Minor improvements that don't affect architecture.
