My idea is to keep /bloodhound/products untouched, so the BH product
would appear there just like any other, and we'd of course change all
URLs in our docs to the new scheme. The reason to also expose that
product environment under /bloodhound is to make historical URLs (in
mails, tickets, etc) work; that'd be just a bit different than in other
BH deployments, but I wouldn't worry about that.

So the full proposal is:

  * /bloodhound/main exposes the global environment
  * /bloodhound/main/products (and similar weird combinations) are blocked
  * /bloodhound/products is treated as the regular product prefix
  * /bloodhound/** redirects to /bloodhound/products/BLOODHOUND/**
    (or whatever you want the product prefix to be)

By far the easiest way to do that is to map the WSGI to a virtual host
bound to localhost, then rewrite-proxy the externally visible vhost to
the real one. Though I'm not sure how that'll work with SSL and
authentication; depends on Bloodhound/trac's capabilities there. I
suspect we'd need at least 'ProxyPreserveHost on' in the configuration.
