No, it is not a requirement, provided of course that the contribution
is released under the requisite license. The most convenient (for us)
way to do that would probably be to fork and release an updated
version on github. However direct contributions would also work
provided we had a way to ensure the contribution is licensed
appropriately.

It depends on what you mean by 'contributions'. If you mean 'something
that will be merged into the official distribution' then it's both a
legal (as above) and logistical question; specifically, is the
contribution both suitable for inclusion and a desirable addition?

If they are provided under said license, I am not aware of any way
they could be re-licensed short of the contributor granting rights to
do so.

The company is registered here in Australia as a regular incorporated
Pty. Ltd. It does not have any 'business model' per se as it does not
sell anything nor receive funds.

> Is POV-Ray Ltd a registered non-profit? 

No. Ironically one of the reasons it is not is that it doesn't make
enough money (specifically, none at all), meaning it would not make
sense to spend the money to try to gain such registration.

Historically we have not solicited funds. On the occasions people have
kindly offered to help, we have either declined or pointed them
towards other means of assistance (e.g. purchasing hardware). We do
from time to time feature wish lists for team members on the site
(usually for things such as programming books or whatever).

Any issues would be dealt with on a case-by-case basis.

I'd have to look into this.

Thanks for the pointers, I'll take a look at them.
