I did travel abroad over Christmas and took my pipes. Here are my experiences:
1) I packed my pipes in a shock proof sleeve (http://www.hardcandycases.com/ipad-bubblesleeve.html), I know it says iPad but its perfect for protecting 8-10 pipes in hand luggage.
2) A small (BIC) lighter or a pack of matches is fine when on your person. I left my expensive lighter at home because I was afraid they'd take it at security but no one even took a second glance at my smoking utensils and I went through 4 different security checkpoints in different countries. However they were truly obsessed with scanning my camera and laptop for bombs. They were also not interested at all in the Czech tool, go figure.
3) I packed a small supply of my favourite blends in 50 calories ziplock bags. About a week worth, ca 14 bowls. Buying tobacco was a nice experience in Germany, Belgium, Netherlands and France. In larger populated areas there was a good number of tobacconists with sometimes stunning selections of pipe tobacco.
4) Ask the locals about the smoking laws, there does not seem to be an EU wide law, but local provinces and towns seemed to regulate where and when and what to smoke by whom. France was always quite open to smoking everywhere but you never know in this time and age.
When in France make sure to visit the birthplace of pipes in St Claude there are a lot of local artisans still working on handmade pipes and they give tours and sell them for fantastic prices!
