Dennis, "/" is not a valid signal name character in Verilog. It also is used as a directory name separator, which could lead to problems in some cases.
If you don't want to use the same names in other tools or languages, then you are more free. Certainly "/" works in Protel, as does "~". I'm not sure what other character might work. I prefer to just play it safe. Even if I don't think I will be exporting my netlist to some other tool, I may down the road change my mind, and not having funny characters in the net names protects me from all sorts of unfunny funniness that might ensue.
