The "real" southernmost point of mainland Asia -- that is, one that doesn't require crossing two bridges and a causeway to get to -- is Tanjung Piai, Malaysia.
And while it'll be a good long while until you can travel from Europe to Asia via India, the long route via Russia and China is almost ready. At the moment, the only problem is hopping over from Vietnam to Thailand, as neither Cambodia nor Laos have workable rail networks. Fortunately, both countries are actively working on rectifying the situation, so with any luck it might be possible in as little as 5 years.
