open source security:
first of all, there\'s a few things that we have to make clear. open source is just the source (=programming) code to which anyone (or anyone under some restrictions) can look at, or use it. most programmes or games don\'t run directly from the source (code), you have to compile it (possible exceptions: things made in python, svg, and so on). you play a binary version of that programme, compiled for your structure and operating system, and sometimes even other dependancies (optional libraries, etc.). so, in the end run, everyone runs a binary, which is just as hard to tweak as the closed-source binary - i mean a binary\'s a binary :rolleyes:
hmm, have you ever wondered why so many servers run apache and mysql? both are open-sourced and i don\'t remember them having any more problems then some expensive MS server ms-sql or oracle, novell servers.
plus there\'s even a security benefit: since the code\'s open, the bugs are easier to be pinpointed and thus easier and faster fixed

of course the bugs are theoretically harder to be found in a closed source, but when they\'re found and exploited, the developers have a harder time pinpointing where the problem is.
so, i wouldn\'t just go around and freaking out, because i use something that\'s open source ...in fact, i\'m using (almost) only open-source applications and games, and i have to say that i had less problems then my brother on the same PC with windows

also, open source brings freedom: if you like what you see, you can just take that peice of code, or the whole code and tweak it to suit you or to make a new programme or game. of course you have to aknowledge the author of the original programme and (in most cases) license your code with the same license (free and open in most cases).
security in planeshift:
planeshift\'s (trying to be) made, so that even if you tweak your client, you won\'t be able to cheat (well, except probably if you hook up an AI system with the PS client ...but that\'d be possible even if it weren\'d open-sourced)
most importaint things are carried on on the server side, which is just as hard to hack as any server from a closed-source game.
...oh, and while we\'re at it ...try to hack your PS cleint ...or if you\'re very enthusiastic, try to hack the PS server

...you\'ll see how much \"easier\" it is

...i alow you even to use cheating apps and search the internet for PS server exploits ...have fun trying :]
in conclusion, i\'m pretty sure that cheating in PS or even hacking it is just as hard as any other MMORPG, just the bugs and holes are likely to be fixed sooner. plus it gives you freedom to tweak your client as you\'d like it - there\'s a few threads on how to tweak your character\'s look and how to tweak the look and feel of the GUI ...well, i don\'t see any harm in THAT :]
...just sit back, and enjoy your stay here at PS ...and if something bad happens, say it, and it\'ll get fixed :]
