Surely Digium can construct a better system?
well you could patch your system to allow mac addr changes, which is not always a good thing since you may have the real mac address on a different system, you could write a library that is loaded with LD_PRELOAD or whatever that maps certain calls used by the codec to get the mac address so it always returns what you want (systrace is an example of remapping calls like this although that is likely overkill for this example). You could change the codec binary to bypass the check, its only a couple bytes. All of this lets you alter the licensing model, I am not saying to do this to avoid getting licenses in the first place (and in fact the first two methods require a valid license at some point) but it lets you decide which system that license runs on. I didnt see a EULA that forbids this, but then I didnt look either, so you may want to be careful with that if you choose any of these methods. -- Trixter http://www.0xdecafbad.com Bret McDanel Belfast IE +44 28 9099 6461 DE +49 801 777 555 3402 Utrecht NL +31 306 553058 US WA +1 360 207 0479 US NY +1 516 687 5200 FreeWorldDialup: 635378 http://www.trxtel.com we pay you to terminate calls with us!
