Virtualbox seems like an application that belongs here...
You are here
Virtualbox
Here:

And here:

If I remember correctly, the problem with it is that it requires drivers to be installed for it to work, and admin access is needed to install drivers. It might be possible to make it portable, but it's utility is limited because of the admin access, just like TrueCrypt.
Sorry for not doing my homework... would be nice though...
it is kinda messy thogh. also, as far as i know, no one at PApps did it. but if you want it it is locatd Here.

Yeah, I should be updating the first post. I'll do it shortly.
