I posted a few Minecraft Portable dev tests a while back. I have reset the version number and remade it with PAL. Have fun!
Description: "Minecraft is a game about placing blocks while running from skeletons. Or something like that.."
Download Minecraft Portable 22.214.171.124 Development Test 1 [0.5MB download / 9.9MB installed]
Download Minecraft Server Portable 126.96.36.199 Development Test 1 [0.4MB download / 2.2MB installed]
Keep in mind Minecraft worlds can be quite big! I recommend setting aside at least 500mb per world just to be safe. Otherwise be sure to monitor your disk usage carefully.
As with all Portable Apps, locally-running programs may interfere or modify the program while it runs. In particular a local Dropbox confusedly ends up writing a file to your Minecraft Portable Data directory. Fortunately it is a just a single small file. You can delete it if it bothers you.
The first time you run either server/client you will need to be connected to the internet to download required files. The server can then run offline, the client will need to be set to remember your login credentials to play offline, IIRC.
Development Test 1 (2012-01-17):
