new remailer, and I see problems

I just got mixminion installed and running, but not published. What tests 
should I do before publishing it?

The mixminiond.conf has a space for my IP address. Mine is a long-term-stable 
dynamic address; it could change if the power goes out or if my ISP 
rearranges cables, but otherwise stays the same for a year or more. I left 
the space blank and got an error; the computer running mixminion is behind 
NAT. I set it to ixazon.dynip.com and got another error. I had no problem 
leaving it blank in Tor; it correctly guessed my external address by 
connecting to something. Can you make Mixminion do the same? It would help 
people on dynamic address (I know of an ISP in Germany that changes 
everyone's address once a day) or behind NAT run remailers.

The default lifetime of a SURB is 7 days. The grace period when changing keys 
is 1 day. Let's say Alice generates some SURBs on the 14th and sends them to 
Bob. One of them goes through cside, dizum, eelbash, and frog. Dizum's key 
expires on the 15th, but he accepts messages enciphered to the old key until 
the 16th. Bob uses the SURB on the 18th. It has not expired, according to its 
expiration date, but it will fail, because dizum has changed his key. I think 
the default grace period should be at least 7 days, to prevent this scenario.
