Maoz Inon, proprietor of the Fauzi Azar Inn in Nazareth and longtime proponent of the INT, has created a website that serves as a central location for people who are looking for hostels in Israel. ILH -- Israel Hostels has a list of hostels across Israel that meet certain quality and price standards for travelers who are looking for good and inexpensive places to stay.
Not all of the hostels are along the INT, but several of them are, so this is useful for potential INT hikers when planning a trip. It's a good way to ensure that you're getting the best experience for your money.
The website is great and it's growing on an almost-daily basis. You can take a look at www.hostels-israel.com.
