Where to host ChezScheme boot images

[Aleksej Lebedev <root%zta.lk@localhost>]

Hi, everyone!

I just added ChezScheme (https://cisco.github.io/ChezScheme/) to 
pkgsrc/wip.

I only checked it on Linux, although I expect it to work on Mac OS X as 
well.

Now I am working on porting it to BSDs. In fact, I already ported it to 
DragonflyBSD
except that there are a few tests failing.

Anyway, for BSDs it needs binary bootstrap images (it's written in 
itself).

Actually ChezScheme used to support {Net,Free,Open}BSD out of the box, 
but now
they removed bootstrap images from the repo. These images are very easy 
to rebuild
on any currently supported platform, for example Linux, but
in this case they need to be fetched separately by pkgsrc.

My question is where to host them? I can host them on my personal 
server, but is it
considered OK when pkgsrc fetches binary distfiles from unofficial 
places?

I know it's only submitted to wip yet, but what is the right solution in 
general?
