Paul:
I will admit up front that I have no idea what you're trying to accomplish, and I am just throwing things out in an attempt to be helpful. Here is my bow-legged wisdom on the subject:
It seems like you are saying that having a home network is cost-prohibitive.
My home computer is a refurbished eMachine from TigerDirect.com. Right now, $299.00 gets you an Intel Pentium-D 925 3.0GHz, 1GB of DDR2, with a 250GB hard drive!
Now, add a minimal DSL charge (well, it's cheap in Arkansas), and FREE LogMeIn, and you're working from home!
Now, if you and Nancy both want to work from home, just add a crummy little LinkSys wireless router (like mine) from Wal-mart, which costs about $40.00, and you can bring that laptop home (I assume it has a wireless card), and you and Nancy can both be logged on from home and doing your thing.
Now, $1.00 is not cheap if you don't have $1.00, but it's just not that expensive to have LogMeIn-style access from home.
