Hello,<div><br></div><div>We developed our own RDP-like protocol for use with WPF. It's quite naïve (take IFrameBuffer and send PNG's with the changed area, then paint it) but it works fine for LANs, which is our use case. It's GPL and developed in C#. We developed it for two reasons:</div>
<div><br></div><div>- The most important one: it was impossible to OEM license VirtualBox. We contacted Sun, then Oracle, multiple times for years. In the end, our product was ready to sell and still had no OEM licensing rates (just a "you can distribute it for free for now")</div>
<div>- Also important: embedding the RDP ActiveX in WPF causes all sorts of problems. We literally spent man-months debugging this and implementing all kind of workarounds. Our own implementation was ready in less than a week by one person.</div>
<div><br></div><div>Maybe KickStarting a fully opensource (BSD license, please) Guest Additions would get traction.</div><div><br>What worries me is whether an initiative like this would definitely kill VirtualBox. Oracle recently nixed every virtualization product it inherited from Sun but VirtualBox.</div>

vbox developers and users,<br><br>i would like to get the proprietary parts, especially the VirtualBox <br>Extension Pack, open source. most of VirtualBox is already open source, <br>which is a good thing in several regards:<br>
- quality of distro integration and<br>- debugging<br><br>getting basic OSE virtualbox support is straight forward and better than <br>any other solution i tried (i'm on linux, i tried vmware/libvirt) for <br>desktop virtualization.<br>
<br>in contrast to OSE virtualbox, installing VBox extension pack is a PITA:<br>- <a rel="nofollow" href="http://nixos.org/wiki/Installing_VirtualBox_on_NixOS" target="_blank">http://nixos.org/wiki/Installing_VirtualBox_on_NixOS</a><br>

<br>it usually forces me to manually download the extension pack which <br>interrupts my whole upgrade process. and i have to do that on each <br>upgrade of my system which really costs a lot of time. so here is my <br>proposal:<br>
<br>we try to get the 'USB 2.0 support codebase' of the 'VirtualBox <br>Extension Pack' open source!<br><br>VirtualBox Extension Pack consists of:<br>* support for USB 2.0 devices<br>* VirtualBox RDP and PXE boot for Intel cards<br>
* VirtualBox Remote Desktop Protocol (VRDP) support<br>* Experimental support for PCI passthrough on Linux hosts<br><br>i would like to start with the USB 2.0 support becoming open source and <br>i think we have several options:<br>
<br>== 1 ==<br>oracle releases the 'oracle USB 2.0 codebase' as GPL for free - is that <br>an option?<br><br>== 2 ==<br>we
finance the 'oracle USB 2.0 codebase' GPL release via
kickstarter <br>(how much would oracle want for their code?)<br><br>== 3 ==<br>we have the specification so we could finance a 'third party GPL USB 2.0 <br>codebase', we could finance this via kickstarter as well<br>
<br>-- <br><br>i would like to have comments on this, especially from oracle.<br><br>thanks to oracle/sun for making virtualbox open source in the first <br>place - i really love your software.<br><br>best wishes,<br>joachim schiele<br>
