also scroll down to the filters/scripts section of this tutorial for some good info..
not sure if that answers your question directly but it's a good place to look into.. I would think it wouldnt be too hard to write a script that filters for customized domains and pipe the output to the terminal in a msg..
oh an 'man etterfilter' has some good info too
still haven't had the time to tackle the sslstrip problem in bt5 but as it seems from the above post 0.9 fixed the issues as suspected. I'll run over to moxies blog and pick it up then install it in the bt5 vm i've been testing with.. i'm still runnin 4 off hd for day to day use until some of the bugs are worked out of 5 but it looks great so far!! i love me some gnome!
