Hi all,

great ideas getting exchanged here between Mike, Jordi and Jeremy...

I think seperation of tasks like Jordi mentioned would be a good think. I also highly 
welcome the idea of datasources by Mike. This would increase flexibility a lot. 

----by Jordi:

> 3- Request transmission time (SYN ACK to ACK of last request packet)
> 4- Latency (ACK of last request packet to 1st response data packet)
> 5- Response reception time

To my knowledge this will not be possible. DNS resolution time is not available with 
Java. Java does not give us access to these lowlevel data. No IP-flags as well. I once 
thought about it myself. The one and only solution I could think of was using JNI. But 
I didn't like the idea because we would loose platform independence with it. If I am 
wrong here I'd be glad to learn better...

Anyway, future plans sound promising.

Greetings,

Wolfram Rittmeyer
