Re: any experiences putting home phone number on internet-connected boat?
You could do that easily with Ooma or Magic Jack (the first is more sophisticated) and having your homr number ported to the device (they charge about $30-40 for doing this). You are hardware dependent then, but as long as you go to VOIP you're going to be hardware dependent. So what?
Either device can be moved to any internet connected computer and you've got your home phone wherever you go.
Ooma (not sure about Magic Jack) can also forward your home calls to your cell phone.
I have Ooma- very reliable, costs about $3/month- mandatory federal taxes.
