Vegas, Windows 2000 And Delta 1010 WDM issue still lingering

Any ideas when Sonic Foundry will release a patch for Vegas
that allows us to upgrade our audio workstations from
Windows ME to Windows 2000. We've been stuck using the non-
secure Windows ME since Sonic Foundry hasn't released this
patch. The fact that some (read most) audio software
companies assume that everyone will be okay on a non-secure
OS is astounding. We'd like to resolve this so our audio
workstations can be secure because some of us have actual
networks that require security considerations.

From the Midiman site (this has been on the Midiman site
for a few months):

Note regarding 2000 WDM Drivers:

When the WDM spec was first released by MS it mandated that
audio had to pass through the internal MS Kmixer in all
cases. The Kmixer unfortunately introduced a 30 ms delay in
any audio that was passed through it. This initially made
the WDM spec appear to be unusable for recording audio
applications since a 30 ms delay is unacceptable for doing
sound on sound. This problem was brought to the attention
of MS and after a few months a “fix” or workaround was
suggested that was acceptable to MS. This fix allowed the
KMixer to be circumvented.

Some software companies have or are now implementing this
work-around in their applications. These should be released
soon as updates or upgrades. Once this fix is implemented,
the latency of audio in these applications is not only
reduced, but can be better than typical latencies
introduced by other Windows-based operating systems/drivers
(VXD, NT etc.). Contact your preferred software company to
find out how they are dealing with this WDM issue.
