A while ago I found a web server which I tried to put onto a USB key. It worked great and took minutes to setup. The real use I can see for this is cd roms of portfolios.

Check out the article on the MBEDTHIS.COM site (me blowing my own horn here).

Basically its a small executable software that doesnt require install and has a really small footprint on the system. This means it can be on an auto run cd with php pages and SQLite databases. 

On the same note I also recently saw on the chattyfig mailing list someone linking to some examples about comunication with flash. the articles were specifically about using a small pc board that has a full webserver funning on it under linux. The coolest thing was the fact that they have a set (and a guide how to achieve it) with wireless network. Imagine sticking this board onto an RC car with a webcamera and using the flash player 8.5 you could stream in the webcamera data and control the RC car. pretty cool with alot of potential uses. Just need the $200US to buy the thing.

Check it out HERE or the article about the wireless network version HERE.  If you got really serious some one there has an example of using GPRS.

Anyways enough geeking out over cool little technologies   I am just looking for a nice problem that I think the flash player 8.5 will solve!
