Counterterrorism Blog is reporting that a relatively small number of South Asian fanatics are headed to Lebanon to cash in and collect their virgins (or raisins). This strikes me as a terrible idea, militarily.
Militaries work when they're coordinated and cohesive. These guys have elan oozing out of their pores, but they have no operational history with Hezbollah. They don't know tactics, communications, and God only knows what weaponry they've trained on. Their command of the local dialect has got to be uncertain, and while I don't know very much Arabic, the risk of accidentally forming a circular firing squad in the heat of battle, by mistaking one word for another, has got to be uncomfortably high. Hundreds of thousands of Lebanese are making the opposite choice, heading north or into Syria, and that probably includes a fair number of Hezbollah leadership. So there's no plan on where to plug these guys into the order of battle.
Israel has found a small number of Hezbollah operatives in the West Bank and Gaza. These guys might effectively take advantage of the relative disorder to infiltrate and conduct suicide missions. But their physical features and their dialect differences will make it hard to hide for very long.
Add Indonesia and Malaysia to the list of governments who are quietly thankful for Israel's doing their heavy lifting.
