We have not tried this yet. From linux-announce mailing list.
This is to announce the availability of a version of Mobile-IP for Linux which has been developed at the State University of New York Binghamton.

The software (along with supporting documentation) is available through anonymous ftp from anchor.cs.binghamton.edu (188.8.131.52) in the file pub/Linux-MobileIP/Linux-MobileIP.tar.gz If you have any questions or comments regarding the software, please follow the guidelines mentioned in mip-doc.ps which is included in the distribution.
