If you do, consider either 1) having the "nosuid" option *also* disallow
access to character and block special files on a file system mounted
"nosuid" (regardless of whether the file system is a local one or an
NFS-mounted one) or 2) providing an option to disallow that access.... 
(We chose 1) here, and I suggested it to Sun as well, complete with
suggested code changes....)
