Dryer vent fun - the repairs

Well after figuring out that there was a complete break in the vent about three feet away from the original hole in the wall, I bravely (read, slowly and carefully) pulled the washer away from the wall and began cutting away at the drywall. I found interesting artifacts like ... a dryer vent hole that had been cut and then poorly patched right behind the washer which, fortunately, was where I had to open up anyway. I found the following to be the situation:

Note the old metal/paper tubing on the ground with the duct tape around one end and the small bit of old white plastic tubing peeking out near the top right part of the hole. The thin metallized tubing had been taped to the original plastic dryer vent, which runs the rest of the way from there, up the basement wall, through the kitchen floor, and out through the brick wall.  We have talked about replacing the entire vent with the proper hard metal pipe from top to bottom, but that means a lot of expense and mess.  We may end up doing that when we re-model our kitchen, since we'll have access to the original tubing again.

Well, this is how everything looks now.

I am going to put up some kind of removable access panel over the big hole behind the washer and try to do a better connection from the dryer to the entry into the wall.

Any suggestions from the peanut gallery?
