Solution: Go to a det where the Americans are present. Thier NIPRNet system gives you virtual web and email facilities (subject to scrutiny by cyber police). If you don't have access to US NIPRNet, just raid their MWR facilities - they practically ooze free internet terminals.
Oh, one small problem - if you are working with our trans-Atlantic Cousins, it probably means that you are somewhere pretty inhospitable.
