What Would You Load onto a Business Card CD?

tkrabec asks: "I have a few of the Business card sized CD-roms, and I have been toying around about what to put on them. I want to make a utility disk that has stuff I commonly use or would find helpful. These CD's will hold about 50 meg I primarily do work with Win32 but I would also like some helpful linux things. I will probably make 2 disks wo get all data/programs I want. I want to put: dos boot.img 1.4Meg for older machines, rawrite 14K to write .img's to floppy's, putty 695K for secure communications, memtest.img 75K for testing for bad memory, fdisk 65K for HD problems, Winzip 1.2Meg for unzipping things. These are just some idea's and I would like some more with some approximate sizes. Also are there any good references that I could put on there as well?"
