I think a similar analogy would be whether you installed on a HDD or SSD. I mean really does it matter? They are both storage media. Just because the location is different doesnt really mean very much.Last edited by duby229; 09 April 2013, 01:31 PM.

Rather than selling a single model at $100,000 you sell the 4-speed version for $80,000 (with an appropriate final drive ratio) and the 5-speed for $120,000, appealing to two different groups of customers. I'm assuming equal per-model sales for simplicity.
All is well, except a group of people on a popular car forum think there's something wrong with the practice and that you should be forced to offer only a single model with all 5 speeds enabled, and assume they would get that model for $80,000. What do you tell them ?

UVD support in open source drivers is big step forward. Thanks to AMD devs for do a great job.
BTW. Discussion about firmware is really funny. Bridgman is right, who cares where microcode is stored (software or hardware), just only a few peoples which think that every soft may be open source, but it's not true. Closed source software haters should look how many contributors from open source projects works at full time on closed source software, because those guys need money for their job. In current world both closed source and open source software has pros and cons. Without closed source software open source software can't exist, because too many programmers will be lose job, so those programmers will be not provide commits for open source projects too.Last edited by nadro; 09 April 2013, 01:20 PM.

I'm still a little confused as to what you guys are talking about. Years ago when R300 was still the shit and was kicking the GF4Ti around, I bought a R9500Pro. I bought it becuase someone figured out how to convert it into a 9700Pro. It simply required a solder point to be made and then the 9700Pro bios could be flashed to the card. It worked perfectly. After that it -was- a 9700Pro. Not too much later somebody figured out how to make a softmod that did more or less the same thing. (I also soldered rheostats to the voltage regulators so I could adjust core voltage and memory voltage. It was pretty cool stuff at the time)
It sounds to me like you guys are talking about something like the above, but making it official in the OSS driver. Obviously that is not something that AMD will ever endorse.Last edited by duby229; 09 April 2013, 12:57 PM.

The boxes for different numbers of users seem to include significantly different hardware (eg memory/processor, redundant power supplies for largest unit etc..).
You need to buy a separate per-user subscription and if it expires then some of the software stops working (the part that is hosted through Digium) and the rest has its configuration frozen.
This doesn't sound at all like what you described, where hardware is the same and only software differences separate the different price/feature points.

Edit: Maybe the example does not quite fit. But there free software is used for market segmentation here. By hacking the software you can achieve a higher number of concurrent calls that is otherwise reserved to the more expensive model.
If you want examples of identical hardware sold with different software at different price points, look no further than servers with bundled RHEL / RHEL AP. The software is free (as in speech), but if you choose to add AP features over the base version, you will lose manufacturer support.
