I use something like this already (Score 1)

I use something like this already except my ISP calls it
a dynamic-shell account. I dial in and connect like any
other user but then I'm able to telnet to the server.

I find it extremely useful. I can check news and e-mail
before downloading it and trash any unwanted messages.
In addition, I can set up procmail filters if I ever
really need to. I can also edit my html on the server
rather than having to ftp any changes. All this and
no additional charge per month.

On the downside of this is that you now have another
account that can be cracked. Though this isn't too
bad because my ISP knows what its doing when it comes
to security.

I definitely have to say that I'm glad I have my
account.
