Thanks for your reply, Drakmor.
Just so that it's clear who the real expert is around here, I'll tell you that Barmaid is a barrister. She works solely in the civil courts but (obviously) has an extremely good understanding of the way that the courts work. I'm nothing more than an amateur, with a keen interest in the workings of the law.
IPPs can only be passed where the offender would be expected to serve a minimum of 2 years in custody. See here:

Licence conditions are theoretically imposed on an individual basis. However there are certain basic rules which seem to be applied to all released offenders. One of these is that the person on licence may not travel abroad. (That's fairly logical because the offender is still technically serving a prison sentence in the UK. So it would make no sense to allow them to travel to a location outside of the jurisdiction of the UK courts, prisons and probation service).
Further to your original question as to what sentence might be imposed (and putting to one side, for the moment, the possibility of an IPP), this might be of help to you:

That's the document which the judge will have before him when considering sentence. (When looking at the tables of sentences, you should remember that they apply to a first-time offender convicted after a trial. A second offence would be likely to increase the sentence. Conversely, an early guilty plea should reduce it).
