Chasing the cloud

In the quest for “everything everywhere” I’ve resolved to only carry my Asus EEE PC and run Windows with all the applications that give me connectivity to all my servers. My only real gripe right now is that I miss Yojimbo or OneNote. I don’t want Office crufting up my XP install and Yojimbo is Mac only right now. I have found a great app for notes called NoteLens but I’m not entirely sure I want them to be local to my machine. This leaves me to install a wiki somewhere, but that has its own issues. Ideally I’d like a personally hosted version of Google Notebook. If anyone knows of a good web based “note application” please let me know! Thanks!
