I'm having roughly the same problem, though without host 1.
I think the right solution would be to add a dyndns option to the
current cipe devel version (which already has a stayalive option).
dyndns would imply dynip, and be most useful when used with stayalive.

The implementation could work roughly like this:
- in ciped.c / mainloop(), re-do the dns lookup if dyndns is specified,
  and tell the kernel module via a (new) SIOCSIFCIPPEER ioctl.
- in device.c / sock.c, handle the ioctl call by calling checkpeer()

I didn't have time to implement it yet, though.
