We should also bundle the new monitor core with a version of gmond that runs on
Windows 2008 r2 as well. The ganglia web front end loses some of it's
monitoring functionality when it can't monitor basic operating systems.
Besides, it only makes sense to keep ALL of the basic components up to date
which includes the collectors too. A nice web UI is useless without all of the
data.

I don't think that is necessary (see my reason below) - people that just
want to have a more up to date web UI can just download the latest
version to their web server, without using the latest gmond code

I think it is workable, but it may add more effort to keep versions
synchronised (e.g. keeping a table listing which combinations of
gmond/gmetad/web are safe)
When you give people a single bundle with everything having one version
number, there will hopefully be less support questions
Another slight variation (although not what I am in favour of) is this:
- keep separate Ganglia-monitor and Ganglia-web repos, as you have have
now, and with different version numbers
- release them separately
- packaging teams (e.g. for Debian) release a `virtual' package, such as
`ganglia-monitor-full' or `ganglia-reporting-suite', that depends on the
real packages
If we are going to go down this path with multiple version numbers, then
maybe version number checking is needed. E.g. I added metrics to
mod_gstatus so it reports agent versions as strings, maybe that should
be enabled by default?
The gmetad XML has a version too:
<GANGLIA_XML VERSION="3.1.7" SOURCE="gmetad">
If the web UI is receiving version numbers for all the gmonds and
gmetads, then it can quickly spot compatibility issues
