Good, so bluez is of the table.

No idea about these two.

Should be fine to build with CONFIG_LIBNL20 set. Its the same codebase as
wpa-supplicant.

Maybe I should get a stab at this as I'm the main user of it in OE. :)

Need to check latest version for libnl2 support. Should not be to hard to change
it.

When I'm going to poke ibrdtn I could take a look here as well. Maybe Dmitry .

Those two have a pretty big code base and I'm not going to dive into it (again).

Need to check latest version for libnl2 support. Should not be to hard to change
it.

As you can see I would be willing to work on some of these. Personally I would
aim for getting the recipes over to libnl2 and the kill libnl1 for good in OE.

Thats one more reason to get rid of the old version. :)
