Only for aos and above. And really, having an installtion program like that that would let you choose expansion, rulesets, maps and moongates, then load/edit the scripts and spawns for the chosen options would be nice.
Also having a GUI like Jeffs working on would be nice, with tabs of stuff, like a maps tab with spawns, player density, etc hell maybe integrated into UOAM or something (altho I don't think thats open source) a graphs tab with various statistics of the server, a tab with on the fly command buttons a la pandora's box, and of course a tab for command line. Scripters could even make custom tabs for their own projects etc. But, thats a LOT of work. Who wants to upgrade Krrios with a larger battery?
EDIT: After further thought, I think using just the bitmaps from UOAM would be legal, being that since the bitmaps are generated from your own client files, He cannot copyright them. Correct me if I'm wrong tho. Altho, using the map viewer from pandoras box would be easier and open source.
