IO STAT for both ethereal and tethereal can already do this.
see manpage
It can however only count the number of times a specific field occurs in the 
captures, not how many
times an expression evaluates to true.


The expression

	foo.bar

evaluates to true if "foo.bar" is present in a frame.
If IO-stat allowed a filter expression, rather than just a field name, to be specified in the "advanced..." graphs, for COUNT(*), it would, I think, be backwards compatible, as per the previous paragraph.
