Pitfalls are usually encountered when running poorly written proprietary apps, but are always able to be worked around. Anything available in a source tarball, or packaged in a repository, will work without any issues though. For example, I ran XLink Kai <http://www.teamxlink.co.uk/> the other day, which is basically and Xbox multiplayer tunneling app, allowing you to set up ad-hoc multiplayer games, bypassing Xbox Live. The app is a proprietary 32-bit Linux binary, which requires wxWindows installed. Because I run 64-bit Linux, when I install the required libwxbase2.6-0 package, kaiengine complained that it couldn't find the libraries. I did have the libraries, but the 64-bit versions. 32-bit applications require 32-bit libraries. So I downloaded the i386 libwxbase2.6-0 package, extracted it relative to kaiengine, and then launched it like this: $ LD_LIBRARY_PATH=/home/jeremy/Applications/kai/usr/lib ./kaiengine Which made the application work fine. On the other hand, some precompiled 32-bit applications (for example, Google Earth, Second Life, or Skype) work fine with no tweaks. My main point in showing you the above example is that while some things may not appear to work, there is always a way to get it working, even if you have to resort to grabbing the odd library (or if you're really screwed, you can run your app in a 32-bit chroot — I for one would be happy to help you set that up if you ever need it).
