We are a little bit disturbed. Not in a "We just watched a David Lynch movie" sort of way, but still, it is a little unnerving to think that our last post on Ulteo hinted at a world domination plot... and now it seems that goal is within their reach.

It is also a little unsettling to eat our words. We read about Ulteo's Virtual Desktop and its claims to run Linux apps quickly and smoothly under Windows. And we thought, "Yeah, right." We've used embedded Linux on Windows before. It works in a pinch, but it's not terribly responsive. It's also a little disorienting to be working in Linux, and then need to manually perform some key combination or mouse gesture to get to a Windows application.

Like andLinux, Ulteo's Virtual Desktop (often referred to with the rather misfortunate name UlteoVD) runs off a coLinux base. There is no virtualization software involved. But we'd especially recommend UlteoVD for those pondering whether a Linux switch could work for them, for a number of reasons.

It's been almost a year since we checked in on Lina, an attempt at creating a cross-platform solution for running Linux applications on pretty much any operating system. At the time, Lina was only available to a handful of folks. Now anyone can download and install Lina on a Windows, OS X, or Linux machine. But to be perfectly honest, we're not sure why anyone would at this point.

Lina definitely shows a lot of promise. It creates a system that will let you install and run custom binaries on any operating system. But right now there's a grand total of one custom binary available. And it's Nano, a simple text editor.

Meanwhile, several other projects have popped up over the last year that let you run Linux applications on Windows. There's andLinux which basically allows you to run a version of Ubuntu from within Windows, allowing you to run any application that can run on Ubuntu. And there's KDE for Windows, which lets you install and run a number of applications designed to run on the KDE desktop environment for Linux. Right now, you can run far more applications using either of these methods than you can with Lina. But we plan to keep checking up on Lina to see if the tool starts to live up to its promise in the future. Thanks to DailyApps for reminding us to check in on Lina's progress this time around.

If you have to use Windows for your day job or for a few must-have applications, but you're a penguin at heart, have we got a program for you. While you can run Linux inside of Windows using virtualization software like VirtualBox or VMWare, andLinux goes a few steps further and essentially installs Linux on top of your Windows operating system, allowing the two to exist side by side and even interact with one another.

In other words, once andLinux is installed, you can launch native Linux applications almost as easily as any Windows program.

AndLinux comes in two varieties the moment. Both are based on Ubuntu, but one installs a full KDE system with all the programs that normally come with Kubuntu. The other version basically installs Xubuntu, which uses the light-weight XFCE desktop environment and packs fewer bells and whistles.

Since andLinux installs a full operating system, you'll need to make sure you've got quite a bit of free space on your hard drive. The KDE version eats up more than 4GB of space while the XFCE version takes about 2GB. If all you want to do is run a single Linux application like Amarok, Ardour, or Cinelerra, you might be better off checking out KDE for Windows and waiting for the developers ro port your favorite applications. But if you want to be able to run any Linux application you like without rebooting, andLinux is worth checking out. Keep in mind, this is beta software, so you might run into issues like applications failing to start
