Oh, well... It would just turn my PDA in a portable webserver that I can take with me wherever people have WiFi available.
And it's not really about it being usable. Just an interesting way to provide temporary access. Of course, you could also use it in a commercial environment. For example, you take your PDA to some company that has WiFi. Your PDA would use their network to call home, and while you are there, the people at that company would have temporary access to this data through the webserver on your PDA. That way, you don't need a highly secured webserver since it's this PDA that will be the only one who can access the data.
Of course, a simple logon page would be required for this customer but hey... It is a way to provide them temporary access to sensitive data! Not to easy to hack into either...

I think I'll wait for PicoWebServer version 2.0, if they ever make it. Then again, only static pages? Well, I have two HTML-based E-books on my PDA. One is from O'Reilly and contains information about XML, XSD, XSLT and more XML-related stuff. The other one is the CIA Worldbook from http://www.cia.gov/cia/publications/factbook/index.html which is just interesting. This pico webserver could be used to serve these two e-books.

The interesting concept behind it is that I can normally use the browser on my PDA to view these pages, although it doesn't look very well. But when there's a WiFi connection, I can use a normal computer and browse to my PDA to see the information. I'll take a look at it, see if it works.
