I would go for distributing binaries for the ladder server admins anyway. This would mean just the 2 dedicated server binaries for x86 and x64 linux architecture, as basically all ladder servers (should) run on such systems. Maybe also a windows binary. I know distributing binaries is bad in general, because:
- only works for one version of Nexuiz
- only supports the architectures that it was compiled for
- issues of trust when giving someone something that is compiled, he doesn't know what's in there
- needs someone who is willing to compile it (I guess I could do it)
the advantages are, however:
- simplicity for the installation: You can
not assume every ladder server admin can setup a compile environment for compiling an engine or gamecode ("can not" either means "no knowledge" or "no time")
- when using binaries instead of patch files, ladder admins who are able to code can not read the patch and benefit from it by circumventing the protection themselves (
don't look at me 
)
- you don't need any promises from ladder server admins to not give anything away if they only have the binary
EDIT: why does the topic say 2.5.3 ? Isn't the next version 2.5.2 ?
