Where were you going 100nm IMC OCAS
To be dropped out of the airways 100nm from your destination is very unusual where was your destination?. If going to the North East Newcastle and Teeside you are dropped out of the airways early Gasko normally (think that is right from memory) but the airports will give u a basic or conflict service OCAS. I think that any aircraft flying in IMC should have a transponder and most responsible glider pilots will agree with that in my experience. That must have been very scary and shows that any further reduction in Services will result one day in a disaster. I will always try and use London Mil in those conditions as another post said they are very helpful but are unlikely to pick up a glider!.
