It is, in fact, trivial to set up a Linux router to speed up your connection to the internet. An average computer can be converted into a speedy router and quite adept firewall appliance rather quickly. Anyone with a moderate level of Linux experience can follow the instructions for setting up an Ubuntu based Linux router. Someone willing to read and follow instructions can build a Linux router with absolutely no experience.

If you deal with code, files, anything important you likely need a third party repository. Most of my stuff is open source or stuff I'm not going to freak out about if someone else sees it. For that stuff, Project Locker has served me well as a Subversion repository I don't have to babysit. I can give a developer access and not worry about potential risks to my central repository. I also use it for clients when I don't want to take responsibility for hosting their code (it's an easy client divorce for those short and unsure contracts).
