Looking for DSP op system feedback

We will be using a DSP processor to do a number of different
tasks. Some of the tasks are DSP-related and some are general purpose
CPU tasks. We are considering using a multi-tasking operating system
for the DSP processor.
We've found two operating systems that look like good candidates:
1) The 'SPOX' operating system from Spectron Microsystems, and
2) The 'Nucleus' operating system from Accelerated Technology.
I checked the recently posted FAQ file (thanks for posting this!),
but there was nothing there about DSP operating systems.
Has anyone used or investigated either of these? I know that
'SPOX' has a DSP math library where 'Nucleus' doesn't, but I'm not sure
how much of that math library I'll be using.
Other than the math library and the price lists, I'm having
trouble seeing what the differences are between these two operating
systems.
According to their brochure, the 'Nucleus' operating system is
also offered for a number of DSP and non-DSP processors. Any comments
on it would be welcome, even if the comments were from experience with a
non-DSP processor.
Any recommendations or comments you may have would be appreciated.

I've been asked to post the phone numbers and addresses for
companies that make operating systems that run on DSP processors. Here
are the ones I know of:
'Nucleus RTX' is available from:
Accelerated Technology
P.O. Box 850245
Mobile, Alabama 36685, USA
Phone: (205) 661-5770
Toll free: (800) 468-NUKE
Fax: (205) 661-5788
'SPOX' is available from:
Spectron Microsystems
5266 Hollister Ave
Santa Barbara, CS 93111, USA
Phone: (805) 967-0503
Fax: (805) 683-4995
If you call these people and you don't mind doing this, please
mention that you heard about them "from a posting by Chuck Corley in the
note string 'comp.dsp'". I think this will help raise the visibility of
'comp.dsp' as a DSP communications medium. This will also help me while
I'm trying to get information from them in order to do my evaluation of
the two operating systems.
Perhaps in the future these companies will monitor and participate
in 'comp.dsp' as a result. (I've noticed that some of the leading DSP
suppliers have already done this). Who knows, someday they may even
change a critical policy or add some needed feature as a result ...
Hope that this helps those who requested the information.

I've been bombarded with inquires for the phone number and
address for the companies that make 'SPOX' and 'Nucleus', so there's a
lot of interest in operating systems for DSPs. The 3 or 4 people who wrote
me with their experiences have done without an op system (thank you for
your comments!).
Is there anyone listening who's actually *used* the 'SPOX' or
'Nucleus' operating systems? How did they work for you? Please post or
write your experiences. I'll try to summarize my findings. Thanks in
advance for your response.
