Hi,

I am a engineer at NASA's Ames Research Center's Advanced 
Supercomputing Dvision located in Silicon Valley, CA. I am currently 
researching for proxies for ssh and scp and am curious about Delegate 
and its potential. I am hoping that I can get a better understanding 
by asking some questions.

My basic situation is that I have a group of special computers that 
remote users want to log into, of which I don't want to be exposed to 
the outside world. So I am looking for a proxy/firewall that will act 
as the filter of all these user login and file transfers. We would 
also want to be able to enable secure ftp, scp from our target 
servers to the client and back also in this setup.

The main idea is that we wanted users to feel like they were getting 
transparent ssh/scp/sftp access to our network while actually having 
a trusted box in the middle through which all access requests were 
mediated. 

Do you feel Delegate is an appropriate solution? What issues/concerns 
do you have in mind? You have specified that it supports all TCP 
protocols, which includes ssh, correct? Would users have to install 
Delegate as a client side program? Are there other requirements on 
the user side?

I truly appreciate all your help and time. Thanks in advance.
