Make the Linux driver open source and get it into the kernel
If the DisplayLink driver existed in the kernel, it would be SO much easier for the users to get it working. In my role as Chief Digital Officer for a large company (of 8000 people), I would probably have bought 500 of these devices IF the driver were just upstream (you know, how Linux devices normally "just work" without the aggro common in the Windows world). However, the annoyance of a manual driver install, especially when it's broken on updates to newer kernels, is just something I wouldn't want to invest in. Please consider that proprietary drivers are serious impediment to sales, and just work with a willing community upstream.

I would think having it as a module would be more supportive over multiple kernels. This way you dont have to recompile a kernel for each distro just compile the module for the kernel WHy NVIDIA, AMD and VMWARE do it.

Is there a chance displaylink could try to add the driver into mainline kernel (except the binary bits ofcourse), this way more distros and users could use it without problems, also community would probably help with development and maintenance.
