TortoiseSVN import similar to TortoiseCVS make new module?

Hello,

I've used CVS and the TortoiseCVS client for years and I'm just moving over
to subversion with TortoiseSVN. I wanted to run my thoughts by the list and
see if I'm understanding things correctly.

I've got two groups of developers who work on different sets of projects.
I'm thinking of arranging my repositories like this:

/developer_group_1
  /project_1
    /trunk
    /branch
  /project_2
    /trunk
    /branch
  /project_3
    /trunk
    /branch

/developer_group_2
  /project_A
    /trunk
    /branch
  /project_B
    /trunk
    /branch

So as long as I created the "developer_group_1" and "developer_group_2"
repositories, the developers in group 1 could use the import command on the
TortoiseSVN client to import files to "project_1", etc, while developers in
group 2 can do the same in their repository. I believe this would be
similar to our current method of developers creating a new module and then
committing in CVS.

I'm thinking of using 2 repositories because the developers in each group
should not have rights to access the files of the other group. Does this
seem sensible?

Right now the developers are running TortoiseSVN using ssh+svn, but we'll be
enabling webDAV, too.

Thanks a lot,
