I suppose windows users are not as much used/interested/involved into free 
software development workflows, and probably don't bother even lurking on the 
developer mailing lists. They only shout when something breaks :p

From what I understood, since it's part of a scientific event, it's mostly 
toward the CS scientific community, where conferences have quite specific rules.

The scientific "community" is only starting to grasp the idea of open work, 
they are more used to do things in their lab and only reveal stuff when it's 
time to publish, and often do not even talk about what doesn't concern their 
direct subject research, so often they use/contribute/write software without 
others knowing.
(it was one of the main subjects of the fOSSa conference this month btw 
<http://fossa2010.inrialpes.fr/>)

That's good to hear, I only found out about the beagleboard qemu fork months 
after having to stick to the verdex target while having a overo gumstix 
hardware :p

As long as patches do not take 3 years to get in like my wacom-tablet fixes ;)

As I said to them, I'd be happy to talk about our usage patterns and needs with 
Haiku development, but I don't know enough of QEMU's internals to detail this.

As I said, scientific conferences have a quite specific set of rules, one being 
you pay to talk :p
Usually the labs handle the expense for the attendees, because this gives them 
exposure.
It's quite different from the FOSDEM or RMLL confs with free entry and best 
effort speaker reimbursement by sponsors :D

Again, the virtualization devroom should give quite a lot of opportunities.
