Can an IE8 Accelerator be made to launch a process?

Question

I want to create an IE8 Accelerator that will launch Remote Desktop (mstsc) with the hostname being the selected text. But the accelerators I've seen only direct the browser to URLs. Can an Accelerator launch mstsc.exe?

Answer 1

Apparently the only thing you are able to "launch" are URLs, as described here.

Answer 2

It can do pretty much anything.
