Do you see Condor being deployed in a seti@home/distributed.net way? I mean,
desktop computers in the wild connecting back to a central server.
SETI@home lets you run a single program on a computer. Condor lets you run
any program you want on a computer.
Granted, you can set it up so that Condor will run jobs as the nobody user
(on Unix--there's something similar on Windows), so they are relatively
safe. But as a random user in the world, why would I trust you to run any
program you want on my computer?
It is easier to gain trust in a specific community rather than in entire world.
