I think that there is an issue that you will have if you use the settings from Baptiste's excellent blog post. As you are using individual XP instances rather than terminal servers, you will have login collisions where somebody who connects "steals" somebody else's active connection, and the active connection is dropped.
I would investigate using balance leastconn and not use cookie persistence to reduce login collisions. If you had a dedicated VM per remote user, then the RWW (Remote Web Workplace) from SBS 2008 or 2011 would be a perfect fit. RWW provides the ability to filter which "desktops" a remote user can access, so you could have a dedicated VM per user and avoid the login collision issue, however SBS won't go into an existing domain.. Have you looked at multipoint server ?
