You make a good point.  As I understand it though, there are many people
who can and would be willing to put the applet in their web pages but
would not be able to place the server backend on their server (like maybe
their ISP won't let them).  The server I proposed above was for just such
a purpose.  Their web pages could reference the applet on
rc5java.spidertrap.com.  Almost like plug and play.

One idea I had was to use the flush command of the current rc5 clients.
If somebody knows the file format of the buff-in and buff-out files then
the server backend would use those files to 'fetch and upload' keys from.
Then execute a 'real' rc5 client to flush the buffers.  Probably not the
cleanest way of doing it though.

I'm sure many people are going to have many ideas on this.  Let's hear
