I'm also doing the MSc at Heriot Watt but by distance learning. If you can afford the fees its a good way to get into the industry (I hope!). There are many more people doing the course from around the world than the UK and Ireland, with Indians and Americans making up a large number as UpsidedownA says. Lots of people seem to be interested in the distilling side of things more, which surprised me as there is only one distilling module, but apparently its the only course in the world that will give you a MSc level qualification in distilling. Most, if not all of the graduates from last year got jobs in the industry. Its a good way of networking with people as well. The fees for new distance learners have just been increased quite substantially though, luckily not for existing students as it would be to much for me.
Other options are IBD exams which you can also do by distance learning, details are on their website, and Nottingham has a newish distance learning brewing course that was set up by Katherine Smart and looks very good. You'll need a relavent first degree though. The VLB course in Berlin is highly regarded but expensive and booked out well in advance, not sure when the next slots available would be but might not be until next year or even the year after.
Without some kind of training or qualification its going to be a case of being in the right place at the right time. A few of the Irish breweries have taken people on that I don't think had any specific experience, but they were local to them. As more micros open there could be opportunities that come up in your area so keep looking.
