group write permission when using bzr+ssh

[S. L.]

Hello,

is there some way to get group write permissions for remote repositories without
changing the user's umask?

example:

my remote repos directory:

    drwxrws---    3 root src    4096 Jul  5 19:10 repos

i try to create new repository from my local machine with:

    bzr init-repo bzr+ssh://www.example.com/repos/test

Now the files and directories will be group-owned by src, but they are write 
restricted, and i can't write to repos with other accounts.
