SVK and plugins

For a long time I was a subversion user, I always used Piston to manage
plugins. After doing more research on version control systems I have
decided to start using SVK (mentioned by the Piston author).

I am curious, how are the other people out there using SVK managing
vendor/plugins directory? I’m relatively new to SVK, but it seems like
someone has dealt with this before.
