Well lots of things have happened. Looks like after about four months, tcpreplay will finally be released in a few weeks. This is a really big thing as I've basically had to put futher development on hold until the 1.1 release is out the door.
I'm also looking into adding a massive new feature- a curses based interactive mode. Not sure how big of a project this is going to turn out to be, but it's looking to be the most complex bit of C code I've ever written by far.
I've also bought a Tivo (one of the AT&T models) and I must say I love the thing. Went out and got myself a 120GB harddisk for it and now I've got 197hrs of capacity... no idea what I'll do with all that time though :-)
