Subject Re: Redistributing 3rd party code licensed under Apache License 2.0
Date Wed, 06 Feb 2013 00:08:36 GMT
Hi guys,

My company is writing and maintaining the current OpenStack Nova Hyper-V driver.  We are also
working on a CloudStack Hyper-V driver, I'd be glad to contribute the code that we have and
our experience with Hyper-V. Unfortunately due to our commitment on OpenStack, we didn't manage
to finish it yet, but I'd be very glad if we could join your efforts on that.

If possible, we would also be happy to contribute our OpenStack Python code referenced in
this thread.

My IRC nick on Freenode is alexpilotti in case you'd like to have a talk about it.
