i am interested in giving dirvish a home on toasterz.org servers or wherever...
it's behind my Easy-BACK network backup product so i have a vested
interest in it moving forward..

i can provide all sorts of community building features or whatever the
community wants.
perl is one of the languages i pursue.

best regards,

>> What is the status of dirvish version 1.3.1?  The website still lists it
>> as 'experimental' and not ready for production.  I tried to look for a
>> changelog for 1.3.1 and I seem to be going in circles on the website.
>> OH!!!  ok.. I downloaded the 1.3.1 tar.gz and looked at the changelog in
>> there.    Hmm... 1.3.1 seems to be approaching an age of three years old.

> a few milliwatts of UV image to control 10's of watts of visible light.

> wide-spectrum images, more energy efficient, no moving parts, no exotic

> time a picture tube burns out or a television is discarded.
> Sadly, high defect density in the read valves (a few dozen spots per
