I think most of the companies i mentioned already employ devs to work on
projects relevant to those organisations. If they could each give one person
half a week to Base
Sure - but if they could each give one person have a week to: improving
the UI, accelerating import, fixing most annoying bugs, creating unit
tests, ... < insert any number of potential problems > - then we could
also make progress.
However - instead of this, we have people complaining and trying to
tell other people what to do
That actually kills developer time,
because they have to respond to the griping by pointing out the obvious
lack of resources, the way that reality is shaped - and asking people to
be more constructive with their time - by actually getting involved
fixing things.
If some of those companies had direct control over half a dev
So - if some individuals, who have direct control over their own work
schedule, could sit down and contribute then we'd get a long way too 
right ?
I don't think TDF can afford to wait until people get annoyed enough (as RMS
suggests) because it's easier for people to just stay with other products and
the rest of the Suite they come with. A little work and leadership in taking
Base forwards might even attract a lot of volunteers to it instead or runing for
the hills.
So - go for it ! you want to win eternal fame & glory, and find
yourself a well paid job hacking base: sign up now - get experienced
with the code, improve it, make noise about your success.
Failing that - your resourcing concerns belong on a single list: the
discuss list.
Most of the co-operatives i have worked in have paid consultants, part-time
workers, accountants, lawyers and all the rest when and where needed.
Many of the ones that refused to do so folded or got absorbed.
Fine - so start a co-operative to work on LibreOffice, and fund these
guys to do the work you want to tell them to do, and to meet your
particular priorities. Failing that, do some fund raising yourself to
get an existing bespoke development company (say Lanedo) to do the work
for you.
All the best,
Michael.
