Bothersome public key SCP implementations..

Subject: Bothersome public key SCP implementations..

This is a general question for those who might be knowledgeable in SCP/SSH file 
transfers.

I am currently trying to setup a very secure method of transfering files 
between users and thier webhosting directories under BSD. As is, the owner of 
the hosting does not want FTP to be used, period.  With good reason, as I agree 
that it is a horribly insecure protocol. 

Right now our SSHd is using SSH2 DSA public key authentication, which works 
very well when the time is taken to set it up correctly between the clients and 
the servers.

One idea that I had is the use of SCP/SSH file transfers, to get around the FTP 
limitation.   However, as easy as this can be done though *nix, its a big pain 
in the ass to use while in Windows. The free, open-source implementations that 
I have run across (FileZilla, WinSCP) seem to use the same PuTTY codebase, 
which doesn't have native support for public key exchange, and relies on a 
secondary PuTTY utility (pageant) for the exchange of keys.

Now this is a bit of a pain. But, to make matters worse, PuTTy doesn't use the 
standard OpenSSH key format, but thier own format, and users have to use a 3rd 
utility (puttygen) to convert between the two.

So what I've been trying to setup, and pulling my hair out with, is the 
wonkyness of having to create, convert, and deploy private/public key pairs to 
my handful of users. Plus, getting said users to run Pageant when connecting 
using FileZilla or WinSCP.

So, I guess the question is, has anyone run into the same problems such as 
this, and if so, what did you do to make it easier?  If not, what would you 
suggest?  And also, are there ANY open source/freeware windows GUI clients to 
make use of SCP with SSH2 DSA key authentication or am I just asking for far 
too much for the price of nothing?

Anyway, glad this mailing list is here, hope to learn something soon. :)
