Papering ceilings, although daunting at first are pretty easy. No obstacles to go round. I paper them on my own usually although using vinyl that width (as seen on the vid) I'd recommend enlisitng help
Likewise, no problem with standard width papers, until you get a load of those crappy recessed ceiling lights in a stairwell

Over the years I've cross lined some mega lath and plaster ceilings, but the past couple of months I have been presented with several ceilings that have been so bad i have had them overboarded and skimmed. Not exactly a traditional solution, but my plastering mate does a neat and tidy job in less time than I could repair and sand and ...
If a lath and plaster ceiling is water damaged the weight of wet lining paper can actually be the final straw to bring them down. That happened once, an architect specified scrim-backed lining paper on a ceiling, it was on his own house. I did the job, went to work the next morning to paint it but instead, I had to tell him to order a skip, a shovel and a labourer to remove the debris in the middle of the floor.
