Sorry, I should have re-read the thing before commenting, because of the
rather ill-defined `standards' business (which refers to a location for
non-existent binaries with which you're supposed to inter-operate).
Presumably maintaining interoperability with 6.2u5 would count, but I
suspect that clause should just be ignored, especially as we're
specifically interested in free software.

Sure (I used OS\370), but there's no sanity in software patents and
legal threats, at least in the USA.

Everything in the repo is under the SISSL as
far as I can tell, although I think some of the Java stuff it depends on
is non-free -- webconsole for a start, but also some required packages.
The SISSL has a patent licence, but the exact consequences of the
language are unclear to me.
