+1 for the list JJ sent.  That is also what I use to try to track down client 
support.  I do agree having an r and k column would be nice, but there are also 
pcaps there if you want to get into a specific one and look.  

It's the best list I know of so if anyone has another I'd also be interested in 
seeing it to have it as a resource.

That being said we haven't run into many issues with r/k/v.  Cisco+apple did 
get a bit finicky about roaming for awhile there, but we are no long a cisco 
shop so can't chime in if it's a lot better or not.  From client side I haven't 
run into issues with these on in our higher ed environment.  I've seen use 
cases where these have broken certain devices but they were wonderful barcode 
scanners.

Eric,
Admittedly I'm skimming here, but wanted to just throw in the note that 
ultimately it's up to whether the client supports the various roaming 
protocols. Not all do, and there's no (IMO) intuitive line there, no pattern or 
specific date, etc. at which point you can easily say "this client would 
support xyz". I'm not cool enough to remember all the details of what all 
clients support. There's some info at

 I refer to regularly - if you pop that out it has the 11v protocol but it 
doesn't look it lists 11k or 11r unfortunately. Someone else here may have 
another resource that's better for roaming info.

+1 on CTS (Clear to Send) podcast links Jethro sent, great peeps and info!

Hope that helps a tiny bit!
