The main issue that I see supporting a mixed DDK and WDK build environment is
that you need to change into multiple directories before building.  I would
think a simple batch file could be used to select the correct sub-directory
before issuing the build command.

For example, once you convert driver X to WDK, you remove its directory from the
parent dirs file.  This removes it from the DDK build.  Then add its directory
into a batch file (say etc\wdkbuild.bat) that can be invoked for building.  Once
all drivers have been converted, we fix-up the dirs files and remove the
wdkbuild.bat file.

Supporting a mixed environment shouldn't be a huge issue.  I would rather see
drivers merged into the trunk sooner.  Otherwise, we end up replacing all of the
drivers in the trunk in one swoop.
