I also just commited check_tcp.

And it's a little know fact that checp_tcp includes the code for
check_ftp, check_imap, check_simap, check_pop, check_nntp, and
check_smtp. So if you symlink to check_tcp under those names, there is
now a fairly large set of plugins that will return performance data for
time.
