digital, sorry to hijack your thread

No problem! It's actually why I like to ask these questions on forums like this (and I have been using them or equiviliants since the old dial-up BBS days). Often it promotes some discussion, which is interesting, informative, and not something you get from just looking up the answer in the docs.
I don't pretend to understand every word of your most recent post, but I get the general idea. It seems that the whole system of RT services outside of CAS is a little bit messy. It also seems the CAA has recognised this and is reviewing.
I suspect the real problem is going to be that there are a lot of legacy systems in place so a complete overhaul might not be realistic, evolution not revolution as they say.
Has anything been published yet regarding the coming changes? Its probably best that I don't read it now because I don't want to let it muddy the waters with respect to my up coming exam, but it would be nice to get ahead of the game with the time is appropriate.
