Yes, that might work, but most finger daemons check the .plan that
it is only a plain text-file, and also do not let control characters
through. Otherwise you have some security problems in your system.
You can with control-characters change the characteristic of the
fingering persons terminal. So, just checking for plain text-files
is not enough.

I sure hope that all finger daemons in the future do this test.
