Actually likewise, G_C, a brief look will be my only involvement for the time being with regards to Bordeaux. I'm more taken with the AndLinux (though not without issues at the moment).
I run XP with Firefox 3.1beta3 but can't easily run it alongside a HDD installed 3.0.9/11, for example. Using AndLinux means I can run two different versions at the same time and simply copy & paste links back & forth. Handy for comparisons.
Impressive, given that one is running in XP, the other in Linux. The Linux applications run on the XP screen just like a native Windows application.
I've allocated Linux 256Mb RAM (above the minimum) on a 1Gb machine and can start/stop Linux at any time (not running as an XP service). Performance is reasonable.
I've installed using the 'lightest' package but think that most people will/would benefit from the KDE interface/menus.
I'll try to make time to look into this further, as with a small guide, this could really be an excellent introduction to Linux for many.
You can run Linux applications alongside Windows ones without any rebooting (apart from during the install).
Before diving in to try this out, if inclined, I recommend to have a good read of the website and understand some of the limitations. Areas in particular include sharing Windows files, Vista and 64-bit systems.
Any helpers, feel free to jump ahead of me. ;-)
