USB booting :: Writeable custom user directory ?

As far as I know you can repartition the pendrive with a fat partition (if you need access to it from Windows) and a second partition with a linux filesystem on which to reinstall DSL. The only problem I can see would be you couldn't access the Linux partition from Windows, even if you had some software installed to read linux partitions...apparently Windows cannot read more than one partition on removable media.

I don't have a pendrive, so I don't know this to be a fact...it's just one of those things I'm pretty sure i read either here or on irc
