Thanks. It seems that to do this properly RT is not the tool - it's just not
architected in that way. Multi-tenant systems I'm familiar with (e.g. Oracle
E-Business Suite) have "striped" data so each tenant is logically separated.
Subject tags, a very basic feature set and a new UI with limited
functionality could possibly get us most of the way there.

For a handful I agree however it is not scalable beyond that in my view.
