This sounds on the face of it to be some really great news, but I think it will only really apply to indoor venues such as village halls etc, where fire regulations etc can be met in order to get the licence. Also, it won't necessarily be that cheap to get the licence, which will be another cost the promoter of the party will have to think about.
However, it is still good news, as it will make it easier for underground parties to take place and to find venues, as at the moment there is a shortage of clubs willing to put underground events on, and so being more able to put parties on in alternative venues is definately a good thing, although with the cost of the licence to take into accout these parties may not necessarily be free.
