A thought (and a non too simple one I'll admit) .. how about developing
a 'light-weight' RT front end talking to a heavy backend.. (might be a
good reason to develop out the the REST interface ;) )

In the mean time I'm going to have to re-think the network design and
hope that my employer doesn't just go 'we'll use a different interface'
and force me onto CTS as I'm trying to get it deployed company wide and
up-root the Salesforce and CTS Ticketing systems that are being
currently used (which needless to say would result in a sizeable
support/devel contract coming BPs way... If you want to know more about
that message me privately/directly.)
