I'd rather add a field in the service menu, with a shell command to be 
executed to decide wehter the menu entry must be displayed or not.
We could have a jolly variable (say "%f") to address the file we've right 
clicked onto, and use it as an argument for shell tests.
The problem with approach (as well as conditional approaches more generally) 
is that the evaluation of a condition might take some time, slowing down (or 
freezing, in some circumstances) the render of the menu.

This is a subcase of b), being a condition on user/host identity.

Anyhow I've noticed an unconsistency in the definition of sevice menus: while 
serviceTypes entries have to be comma-separated (","), the separator for 
Actions entries is a semicolon (";").
How don't understand this choice, as it is quite confusing.
Does it have some historical reason??
