To run transmission full screen, run
/usr/local/bin/wmctrl -r Transmission -b toggle,fullscreen

Thanks to qole for the wmctrl line which i changed slightly.
My wmctrl comes from kotczarny's kciconsbox.

How come you are averse to sharing your debian folder?

You've got me running dh_make, going on packages.debian.org, editing makefiles and extracting files from your deb to package a version with some planned improvements (well, if i can figure out c + gtk... time to grab a stack of c books and go onto the maemo site to learn hildonisation basics...)
