One problem there. Is vsafecsh available for mac, pc/windows, NeXT, OpenVMS,
Amiga ...

Larry's solution had the merit of platform independence which c shell, safe or
otherwise, does not. I mention this in particular because Mac users seem to use
applications like CUSeeMe (?sp) which is, I think, a VAT application.

Limiting to a single platform, in this case Unix, seems undesirable unless there
is no other way. In this case the shell is only launching another application,
so the original MIME type suggestion seems to be the bigger win.
