is the procedure to make et2O from etOH in H2SO4 (@140) an unpleasent experience?
No. Be very careful, but it's quite easy. I do recommend that you have a pressure equalized addition funnel and a vigreux column with an efficient condenser. Make sure to use an oil bath, and run ice-cold water through the condenser. (alternatively, keep the receiving flask in an icebath)
The main objective is to minimize the odor as much as possible. What if she attached a hose (connected to a water aspirator) to her vacuum adapter and turned the water on ever so slightly? How about during reflux?
There is almost no odor when this synth is done correctly.
Or, Should she just run a hose from the vacuum adapter straight down the drain and turn the water on to flush it?
Not necessary, lead the fumes away from anything that could spark.

Why are you doing this procedure. It takes a hell of a lot of energy and time to make your solvents, I recommend you just buy the ether (starting fluid?) unless you're making this ether to huff. In which case, I hope you started from sugar, yeast, and good quality drain cleaner. Enjoy!
Don't break your glassware while huffing this stuff. (doh!) A vacuum adapter and a small flask make an awesome way to inhale the vapours, ensure that you wash it with sodium carbonate or it might taste a bit sour.. (ethyl hydrogen sulfate, yuck!)
