That sounds great, but in my opinion that is just to much resource for one small task. First off I am not a huge fan of Logmein, i prefer to use TeamViewer.. Second, If memory serves me correctly you still have to install some kind of software before using Logmein. Thirdly, Even if you where to use LogMeIn your dependent on connectivy speed, which falls back to resources used. So if you do not have a great connection then trying to remotely access your system can cause some serious lag.
Its a good solution until an applet could be created to allow online editing using your personal WebBrain account. However for me, I am not that desperate yet.
Thanks for the idea though!
