Alternatively you could specifically create a group and user with id's
specified by yourself on all the machines you're sharing with. While
this could be used, it should only be considered (and not for very
long) if you're only working with a couple of machines.

It's a quick and dirty fix which would not at all translate well in a
even slightly bigger environment.

It's a bit like using localised name resolution rather than a DNS.
