As far as tn5250 goes, you could run it in gnome-terminal and get
links highlighted without doing anything to tn5250 itself.

gnome-5250 would have to do something similar to gnome-terminal.

It's be nice to work out the protocol Client Access uses and implement
STRPCCMD that way.   I've always though it could be a small security
risk in some cases, so you'd have to be able to disable it.

RUNRMTCMD uses rexec if you specify *IP in the remote location name,
which is supported under Linux and every other Unix.  You just need to
enable it in /etc/inetd.conf, and supply a username and password for
the Linux box.

I'm pretty sure there's some Linux FTP servers that support running
commands, though I can't recall which ones do. rexec is probably still
better for this, though.

You could look at other protocols like form uploads via CGI, email via
SNDDST to an address that processes the file in the .forward, etc.

Hope this gives you some more ideas, anyway.
