Request Apps

I was thinking that it would be nice to have a portable skype, and I saw a post somewhere about someone asking about using itunes for podcasting while traveling (portable itunes), but these programs are not open sourced so we can't do that, right. So I thought what if we could make a program that treated any application like it was portable, so if you had room you could install skype or itunes on a usb key. What do you think? Is this possible?

My portable interest started with needing to develop my website from multiple locations. See AMP on a USB at http://firepages.com.au/ for more information.

AMP - Apache, MySql, and PHP.

I would like to see a cleaner shut down of Apache and MySql.

Can you make a Portable photoshop cs or cs2.

thanks

How about a portable visual basic or something like it with an open source program?

Need a firewall, freeware, which can be launched from USB without need of installation over the host computer...

Have to be stable too.

What do you think about those?

Does anyone know of a good file synchronization utility out there?
"Super Flexible File Synchronizer" seems to the best synchronization utility I've found yet, but is not freeware.
Or should I look into a simple backup utility.

I move Total Commander on my USB drive. Has changed ini file location (as default in Windows directory) and in all plugin set path %COMMANDER_PATH%\plugin.
The best file manager always with me.

A portable dictionary will be good for people who doesn't know great English. Like me

Do you know Shinux?
It is a Gnu/linux OS available on a usb flash key, downloadable for free, you can buy a key, too.

I didn't test it, but why not register there?
