hmm, thinking about it, did you try awokd's approach? I do something very 
similar for my QubesTV setup that I'm working on polishing, which works on 
scripts too, like we're doing here. The command may have to be adjusted a bit, 
but in general, it should work, even without xclip in dom0. 

Actually, I'd go as far as to say it should most definitely work for xclip, 
while my scripts here are different, I've done it enough to tell it can work if 
modified correctly.

Either way, try awokd's command out, it will definitely work in one variant or 
different. The question is if require a bit of modification. For example, maybe 
use "qvm-run AppVM bash 'command to execute inside AppVM -o etc. lalala'" 
instead of say, "qvm-run AppVM gnome-terminal -e 'command to execute inside 
AppVM -o etc. lalala'". 

For example I've seen a case where one when executed inside the AppVM, will 
open the executed QubesTV streaming link in the same browser, same tab, while 
the very same command inserted into the AppVM from dom0, would open up a whole 
new instance of Firefox, and thereby open a new window. Which, needless to say, 
doesn't work. The solution was to use bash for already running firefox, so that 
it won't start a new firefox instance. Hopefully you can use any of this to 
make qvm-run appvm "command" work.

In terms of security, I'm in the same boat, I can't say for sure. But I agree 
with the notion, that it "probably"? is secure due to the one direction flow of
