Ummmmmm.. I think I'd like to think about that one. On the whole, I'd
have preferred 'horton' to distribute a variant of the fingerd daemon
as a stepping stone to applying for an allocated SERVICE number from
NIC/<whoeveritis> so that this migrates to another port.
That way I know that this traffic is constrained to just that context.
no... I dont trust every host within my local domain. some of these hosts
are TCP/IP terminal servers where connect <host> <port> is legal, so people
can be emulating a range of services by telnet-typing.

This is a dual-edged sword. Deploying something as sensitive as an information
gatherer, without requiring active consent, and to close off access requiring
local modification.... not social behaviour methinks.
I think I'm being too paranoid. This problem probably isn't that big, its
just giving me an itchy feeling.
On the whole, I think (mis)use of finger is doing more good than bad. I'd have
preferred to see the various threads of functionality unravelled a bit more.
