sometimes i like to try programs that i don't know yet, just to be curious.
but i don't want to spoil my clean and verified tce/optional-dir with packages,
that i don't need and don't want to have.
a great thing would be the option to install a package with all it's dependecies just to ram,
without saving to tce.
in the moment i have to clean my tce-repository, after trying some stuff...
for little programs it's no problem at all, but if i try a whole desktop like enlightment or xfce, the fun is gone.
perhaps there is a chance to download packages to /tmp and i can decide afterwards,
whether i want to copy them to my tce/optional-dir for keeping the tested packages...
i hope you see these advantages, that the config stays lean and clean,
but we keep flexible to try other packages perhaps just once.
