Now here's the kicker, I'm very tempted to write a tutorial about the arcane art of PPP/RAS servers. So if enough people (~4) comment that would like to see a full tutorial, then I'll get one together and up by 9/15/05.
Now to ponder the cost of setting up my own ISP. It'll take ~$5000 dollars in hardware to build a box to handle aproximatly 70-96 users (24 nodes), not including the monthly cost of the T1's coming in from the branch telco office.
Oh well, lets see $5000 dollars in startup costs, plus cost of monthly T1 line, for a return of ~$6 dollars per user is $420 dollars a month. (6 * 70 users) Not exactly a finacially good plan. :D
