Qliner Hotkeys portable request?

Qliner hotkeys is an application that allows you to set keys to hotkeys, e.g. if I hit the windows key and a it could open up internet explorer or whatever.

Here is what I thought was a pretty cool idea: perhaps be able to have the hotkeys with you, so like if you hit winkey and W it will open up windirstat portable from your flash drive.

I don't even know if it can be done, but if it can it would be awesome.

Let me know what you think.
