iPad Case for Locking to Furniture?

[Jonathan I Ezor#IM]

We are considering getting my mother an iPad to help keep her company during an extended hospital stay. I would like to be able to secure the iPad via something like a Kensington lock, but since the device itself has no locking slot, I'm wondering whether there's a case that makes such securing easy. Any suggestions would be greatly appreciated. {Jonathan, visiting from PreCentral}
