I have posted and been around the antix community just enough to know that you won't be offending or stepping on toes or pulling anyone away from their focus ..
If anything...
setting up a thread in their community forum on the exploration of antix on arm would be a considerate and polite thing to do since it is after all ...their distro

I think running a thread in our and their community...
showing what developments with antix has achieved on arm and what hasn't will be very interesting...
I think as well...that the casual input and interest by community members there will speed up development for you as well...
since their input will help in chucking some avenues of devel you think may be valid ...but which they know are not..and help steer in a direction for the best outcome...and likewise I believe what their community will learn about arm ...in application ..could be of great value to them as well...

So benefiting both communities

And I am sure that many there will follow such a thread with great interest and throw their experience and wisdom into the thread where and when they can in an effort to illuminate or help. (and that cannot hurt at all)

I don't think you need to worry about stepping on toes or offending any there...
The community there isn't like that...
And I don't think it should be a worry about running a thread ...
as a matter of changing the focus of interest for the antix community...
It is more like ...no one there has either thought to apply antix to arm ..or has the experience in working with arm as our community does...
And don't forget ...one of their prime philosophies and interests for their community IS trying to get antix to run on older hardware ...
In fact all their development in newer antix iterations is focused on making sure that old hardware isn't left behind.. (unlike the mandate for most distros and communities which is to drop the old hardware and software and embrace the new as fast as possible..)
And yet antix as well is a cutting edge rolling release...
fascinating ...really...

So what better example of old hardware is there than the Nxx0 line?

I think it a great idea which would benefit both communities...
and yup ...they definitely could't hurt having an arm distro...
it would bring many more people interested in antix to the community and to ours as well

Of course I do have a motive after all...
My secret agenda in all this...
is a hope for a smooth problem free antix on the Nxx0


Update:
Actually I just recalled...
antix does have some very lean variant versions to install...
which you may find have much more promising results...
