We have extended family, and a couple of families in our church. We also are constantly keeping an ear (eye?) open for information on various programs for work and housing. We also have acreage and have discussed building bunk houses on the property here.
In our will we have designated guardians, with back ups for that, and we've written in that we want extended family input on major decisions regarding the lives of the kids. We have older nieces and nephews who are familiar with our kids' issues and who love them. They may not be able to provide a home for the kids but they will be involved with their care in some capacity should Dh and I be unable to care for the kids.
Frankly, though, if we had to find something RIGHT NOW for adult kids it would be tough. There are very limited options, and I would try to avoid government programs for adults who are unable to live independently. This is my personal bias, of course, but I do have my reasons.
