skype is something i have looked at for quite a while. in conjunction with systems like bitwine and just the work of having a clean voice communication seems to be rather appealing.
i have been looking at the wifi skype phones. if i had someone calling when at home or within range of wifi (work, library, panera), the call comes in. belkin has a phone (though right now the phones are a bit costly). linksys also has a phone that performs the identical function (the iPhone).
both cost around $200, rather flexible and if you are using skype regularly, a very worth while investment (since you do not have to be tied to a computer to converse).
