FWIW ... I've just tried having a look at this myself, and it seems 
pretty trivial to get it running tcptraceroute [with all the right 
parameters] *BUT* it runs into trouble on the last hop where 
tcptraceroute also includes the [open/closed] port information in its 
output as well.

EG - Tracing the path to internode.on.net ( on TCP port 80 
(www), 30 hops max
 1  lns1.mel6.internode.on.net (  15.632 ms
 2  gi1-3.cor1.mel6.internode.on.net (  24.406 ms
 3  gi5-2.cor3.mel4.internode.on.net (  24.678 ms
 4  pos3-0.bdr2.adl2.internode.on.net (  23.701 ms
 5  po2.cor3.adl2.internode.on.net (  22.175 ms
 6  corp.internode.on.net ( [open]  22.669 ms

It seems all that's really standing in my way is the need to strip out 
[or otherwise deal with] that [open/closed] output, and everything would 
be fine.

Unfortunately being someone who really doesn't know much at all about 
coding, that's really beyond my ability to deal with myself.

For someone who actually knows what they're doing though, I imagine that 
really shouldn't be too hard for them to work out would it?
