Okay. Now let me add more fuel to this useless discussion [1]:

http://www.fsf.org/licensing/licenses/agpl-3.0.html

Note, that this license (Affero GPL) seems to be considered a "free, 
copyleft license" by FSF itself.

Still, it restricts the actual *use* (and not just *distribution*) of 
covered software. The exact type of restriction is different from one in 
LinuxSampler license, but that's because it tries to solve a different 
problem.

LinuxSampler license is intended to prevent hardware makers from 
profiting off the LS project by making it a part of hardware box, AGPL 
is intended to prevent Web companies from profiting (in some or other 
way) off projects by combining it with other code and running it on a 
public server.

Similarities:
- intention of prevention of uncooperative behaviour
- restriction of use
- encourages dual-licensing to companies that *really* want to use a 
project in closed source derivatives
- based on GPL

Differences:
- LS bans: commercial && hardware
- AGPL bans: derived works && closed-source modifications && use on 
network servers
