I do tech support. There are a lot of websites out there, some free, some not, which provide services for tech support agents: screen shots, solutions, forums, modem documentation. However, none of them provide wuite what I want, and I'd like to give back to the tech support community(*) what I've learned. So, my goal was to develop a similar website, but more inclusive, and which didn't repeat already existing resources.
Version 2 is a vast improvement. But it wouldn't let me make my tech support site, because a lawyer could grab any money I might have made from ad sales and the like. But I don't work for the company I do tech support for. I'm a contractor for a call center. At any point I could be transfered to handling credit card phone calls, or telemarketing (blech). If the company puts the work of their clients under the umbrella, I could get severly limited. But my contract specifies that the technology that my employer owns is that technology related to the efficient operation of a call center, limited to phone systems, ticket tracking, and some specific kinds of network software. That's it. So my support site is legit.
Since you're going into R and D your in a somewhat more precarious boat. But I think a few well placed generalities will protect most home projects you might go into, while at the same time keeping you a good canidate for you employer.
Also: dws is right on target. The company is being malicious (yet anyway :-). Get all your prior work grandfathered, and be sure that your company is assured that you can't use proprietory information. That should cover things nicely.
