Not very hard at all, I found. That discovery prompted me to write a contact manager based on a tiny Web server written in Perl. Both weigh in at under a megabyte, so can be delivered on a single floppy or by way of a reasonable download. That megabyte includes the local web server, the application logic, and the data. Both run acceptably under Windows 95 on my aging 486-50, 16MB Toshiba notebook.
