I love the idea of inserting creator info for reference... my concern was based on the fact that if someone wanted to hack it, it could be done. (to be honest, someone could whip up a macro in Word or a batch file in 'doze right now that can do it, or this one line in Linux or perhaps even in OSX could knock it out: cat creator.txt >> mynewfile.cr2 - this merely appends your original owner info (the contents of the "creator.txt") to the .cr2 The problem with an ASCII file is that it has to start in ASCII-readable code - even encrypted characters are ASCII-readable before decrypting. If you had an encrypted block, it prolly wouldn't take too much to exchange that block for a "dummy encrypted block", and unless you incorporate CRC checking or some gawdawful stretched-out algorithm, that dummy block would suffice nicely... and, even if you did use CRC-style algorithms, a simple "keygen" style block-generator wouldn't be hard to implement. IOW, I'm not averse to the idea, but it seems like such a waste of CPU cycles, outside of adding author and revision date info (which I myself could have a lot of use for in the modelling department.) Even worse, if you think there are folks who detest Poser 5's registration scheme, they're gonna absolutely hate this one. But all in all, it wouldn't take much to add comment lines denoting who made what and when... I think cr2 files could be made to use the standard "#" character to claim comment lines... /P /P
