Take a look at
Data on Call, $ 10 a month (there are many others Google for efax.,)
they supply a 1-800 number and the fax goes to your designated e-mail box
So you can get it when you want, also you don't have to print if you do not need to.
Scan your signature, drop it into docs, and send it back without printing.,
keep frequently used forms ready and you can fax in seconds.

For Internet access look at a Wireless PC Modem.,
see Fido., you can be online to send and check email on the road and keep cell phone for voice traffic.
$250 PCI card and $60 a month for unlimited dial-up speed internet, coverage not the best check their map for your routes.
Fido and then keep AOL Instant Messenger running on your laptop and your wife kids and office can IM you 24/7 smilie(':9') If you are out/asleep its there when you look.
