Yes I plan to make it a plugin / add-on which can be customized easily, but first I have to make the core application function well enough ;) After that I will start researching how to handle this particular subject. I find it very useful myself so it's on the top of my todo-list :)

It's still far from a beta version, but the program will be freeware no matter what and I will probably publish some alphas and betas on DC to get opinions and bug reports.

@JGP: wow that's a way off result! Look at the round trip time and max pause...
