Basicaly p69 is illegal just as much any other server is illegal, and wemade could sue your isp if needed.
Any server which meets all these requirements is legal;
1) Does not profit (altho can take unlimited donations and recoup server costs)
2) Does not edit the original client AT ALL (it is possible to argue that if settings are contained within a config file, that it is the producers intention for you to edit)
2a) The EULA of the original client may prohibit you from using it on any other server... I wouldn't know as ive never read it.
2b) Other clients which don't use the original material/files/protocol should be fine.
3) Server does not use any of the original code (your m2's use the same protocol as 1.4 MIR), dispite other files being 'emulated'.
Ideally... you want a completely written from scratch client and server, with fresh homemade graphic files. However if its still too like MIR you cannot make a profit as its trademark infrigement. Make it signifficantly different then its fine (and its prolly also a different game by then).
