My main issue is that I don't want to install this kind of software on a computer that is not dedicated for that specific job. If they don't trust me enough to report my work correctly, then why should I trust them when installing proprietary software on my computer? Who knows what else this software is doing, once I install it?

If I had to use this type of software to get a contract, I'd be willing to do it (on a dedicated machine), but the payback would have to be substantial. However, it seems like the gigs that require installing this type of software don't actually pay as well as those that don't.
