Thanks for making this another thread because I didn't read the answers to that patch and I was going to try and implement this (svn:externals via submodules) sooner or later. Hadn't I seen this, we'd probably end up duplicating effort. Maybe I can help with the implementation?

This week I'm probably going to start to dive in git-svn by  
implementing simpler things first:
   - git svn create-ignore (to create one .gitignore per directory  
from the svn:ignore properties.  This has the disadvantage of  
committing the .gitignore during the next dcommit, but when you  
import a repo with tons of ignores (>1000), using git svn show-ignore  
to build .git/info/exclude is *not* a good idea, because things like  
git-status will end up doing >1000 fnmatch *per file* in the repo,  
which leads to git-status taking more than 4s on my Core2Duo 2Ghz 2G  
RAM)
   - git svn propget (to easily retrieve svn properties from withing  
git-svn).  git svn propset would be nice too, but I guess it's harder  
to implement.

Cheers,
