Your idea should work...the only thing I would do is make sure you setup the linksys to only allow your people on.

Personally I havent been able to get my linksys to work with my dell on any of the encryption standards, so I just limit mac addresses. I havent been able to figure out whats going wrong because the laptop will work on campus with the ciscos. So I would look into some of that before I started using it.

From a business perspective I would prolly want to have the encryption working...although weak better then nothing.

Well those are my thoughs for what they are worth
