How can I get 2 RH7.3 systems to see each other from Konqueror?
 

The 2 systems can see each other fine at a network level, i.e. ping, telnet etc. What I want to do is to be able to see the filesystem of one from the other in Konquerors "tree" view and generally from within apps (i.e. "save as.." goes remote). I noticed an option to "browse lan" but that seemed to be restricted to localhost, almost certainly because I haven't configured anything. Thanks!

Well, Linux handles this a bit diefferent than Windows does - I'm sure you know nfs. You have to export a certain folder on the one machine, and on the other, you can then mount this share with mount -t nfs <IP_OF_MACHINE>:<PATH_TO_SHARE> <MOUNT_POINT>
You might have to set permissions in a way, that you can write to that particular share.

I use ftp servers on all machines. Works quite good, too.
