Regarding tags, there's a better way to handle them in subversion:

1) Here's the repo status:

$ pwd

ze_at_ubuntu:trunk$ svn log --limit 3
r6 | ze | 2013-05-19 09:58:38 +0100 (Sun, 19 May 2013) | 1 line

Marked v2
r5 | ze | 2013-05-19 09:56:55 +0100 (Sun, 19 May 2013) | 1 line

Marked v1
r1 | ze | 2013-05-19 09:35:25 +0100 (Sun, 19 May 2013) | 1 line

Initial import

2a) This might be an alias to a "svn tag checkout v1"

$ svn checkout -r5 file:///tmp/repository/trunk wc
D wc/this_repo_state_would_be_v2.txt
A wc/this_repo_state_would_be_v1.txt
Checked out revision 5.

2b) This might be an alias to a "svn tag checkout v2"

$ svn checkout -r6 file:///tmp/repository/trunk wc
A wc/this_repo_state_would_be_v2.txt
A wc/main.c
Checked out revision 6.

These would be proper tags: they are immutable, they take over
essentially zero space in the repository, don't store redundant
information, and are completely free to be created and deleted. No
network traffic is needed.

I suspect that the only thing that would be needed for subversion to
offer proper support for tags is to implement a list that tracked label
names, revision number and the path to a specific subdir tracked by the
subversion repository.
