What you'll need should be in close or done in 0.12. You'll need:
 - Transport emulation turned off. This prevents access to the raw .kndx
etc files.
 - Some sort of policy control noting that the repository contents
should be filtered. This will need a Repository adapter to do the
filtering.

Transport emulation will be an optional on-by-default feature for 0.12 -
right now its the entire functionality of 'bzr server'.

Agreed. We should get one, probably from the IANA.

It already can in principle: just server ~ in this case. However, you
want to be able to limit the served space. The plan is to have a
transport adapter that provides a virtual root, with child transports at
named places - so you'd have a VFSTransport() with /product1 being a
LocalFileTransport at /home/you/product1 and likewise for product2.

Thats not currently in the critical path to implement - perhaps you'd
like to write a patch? I'd be every happy to document what bzr serve
will need such a transport to do, and how to test it.

This is the same issue as accessing over sftp etc at the moment: we have
no defined 'find branches' api. A solution for sftp and ftp will work
for the smart server too.
