OK. I spoke with Michael about you and M3 at Elego, but I haven't
seen an answer from him, so I don't know if he got back to you.

Yes, it's all the same VM currently, but it will probably be migrated
to other servers and services separated.

Yes, you can install any new key you like there.

Hm, I cannot really explain these offhand. Perhaps its best to ship
to a sibling directory and then do a diff -r -b -B old new.

I don't really know one offhand now. As far as I know Github does not
have it's own build service. But Mike has suggested that if you don't
find a suitable service, we can continue to host the CI server. But
he wants to abandon the old and outdated Hudson and install a current
Jenkins system. That would be much easier to maintain, too.

Look at Jenkins, this is the current free open source variant.

That's annoying of course. Excuse my curiosity: where are you located?
