Don't do it now but for a couple of years I worked out of the house doing contract negotiations and dispute resolution. 75% of the communication was done through exchange of documents, the other 25% through teleconference.
More than once there was a multiparty teleconference between Houston / London / Bern or Halden / Paris and either Luanda or Cairo...and good 'ol Los Anchorage.
In my case, I routinely communicated with the Corp office through e-mail, so it was very convenient to be at home on the internet all day. For doing the substantive work, access to the internet to send e-mails to the other parties would only have been needed every 2-4 days or so.
