Chris,
I haven't compared your code with James' but we (Zentific) have been
utilizing Xenstore for some time now from userspace via the GPL pv
drivers for our Windows VM agent.
Certainly, gaining access to grant operations from userspace will be a
nice addition. :)
Many thanks for letting it loose so others might hack away at the code.

Hey all,
About 4-5 months ago, I wrote some userland libraries to go against
James Harper's PV drivers for Windows Xen guests
(http://wiki.xensource.com/xenwiki/XenWindowsGplPv). These provide a
Xenstore, event channel and userland page granting interface very
similar to those provided to Linux apps. I sent patches to James some
months ago, but hearing no feedback for some time I've pushed my patches
to a Github repo.
If anyone's interested in the code, it can be found at
http://github.com/smowton/xen-pv-windows-evtchn
Any questions please email cs448@cam.ac.uk

Chris,
Does this have memory ballooning support?
Thanks,
AP

Would there normally be a userland interface to the balloon driver? My
(admittedly cursory) impression was that ballooning was an act
coordinated between the guest kernel and the hypervisor / control
domain. That would make it a matter entirely of concern to James' drivers.
Looking at his Mercurial log, it seems he's been working on it just a
few weeks ago -- see

Yes ballooning is working in the hg tree. Not well tested though.
