Last month's Linux Journal (I think.  Maybe it was somewhere else 
entirely.) had exactly the solution to this.  There is a tool who's name I 
forget that will effectively do ppp over ssh.  So you set up the ssh 
tunnel between you home and office and then you can route office traffic 
through the ppp tunnel.

The really cute part was at the end of the article.  You set up you office 
box to check to see whether your home system is up evry minute.  Most of 
the time it isn't, but when you boot your home system it makes a secure 
ssh connection and then starts up the new network interface between the 
two systems.

I'll try to look it up this weekend.
