That sounds great. The only problem is that you just have to accept the word of whatever PR person you talk to at these companies. Not that I really expect them to flat out lie to you, but I wouldn't necessarily expect the whole and complete truth either.

Not that that'd be much better than a PR rep, but it'd be easier to get at least.
