Yeah, as Greg mentions, we have access to Visual Studio.
'Actually building svn' on all these platforms will certainly need help from
you guys :)

The master really isn't the problem as far as builds are concerned, the
'waterfall' view may look a little busy when there are long builds mixed in
with short builds for other projects but again I guess it is something that
can be worked on.
There are a few different 'waterfall' views around, the standard one that
comes with buildbot, which subversion uses, there is a view created by the
Mozilla guys I believe it was that the ASF buildbot currently uses, allowing
more information on the page, and there is the chromium.org waterfall view
which I intend to add soon to our views
http://build.chromium.org/buildbot/waterfall/console
so, plenty of choices or we write another one.
