RC4 in TLS is now broken. But the breaking seems to have a lot to do with how web transactions work in general. Is there any application outside of the web where RC4 is still used? I know that WEP is long out of the window. Any other widely used applications?
RC4 seems to be an option in the SSH1 and SSH2 protocols, so yes, it is still in use as cipher. AES seems to be preferred in most configurations, but "arcfour" is still often used as fallback.
WPA and WPA2 may also use RC4 instead of AES, using TKIP. Again, this protocol was introduced to replace the broken WEP protocol while still relying on the faster RC4 protocol. So it's still often used as fallback in case WPA2 with AES is unavailable, e.g. on older hardware without hardware AES support.
