  - High-performance, through a design with multiple worker threads,
    epoll and sendfile (yes, sendfile); a 2GHz quadcore can saturate

-   and the right kernel tuning.
+   10 gigabit Ethernet (even with TLS) given a modern kernel.
  - High-availability. You can change any part of the configuration
    (and even upgrade to a newer version of Cubemap) by changing cubemap.config
    and sending a SIGHUP; all clients will continue as if nothing had happened
    (unless you delete the stream they are watching, of course).
    Cubemap also survives the encoder dying and reconnecting.
- - Per-stream fwmark support, for TCP pacing through tc (separate config needed).
  - Support for setting max pacing rate through the fq packet scheduler
-   (obsoletes the previous point, but depends on Linux 3.13 or newer).
+   (depends on Linux 3.13 or newer).
  - Reflects anything VLC can reflect over HTTP, even the muxes VLC
    has problems reflecting itself (in particular, FLV).
+ - Multicast support, both for sending and receiving (supports only protocols
+   that can go over UDP, e.g. MPEG-TS). Supports both ASM and SSM.
+ - TLS output support, through the TLSe library (requires libtomcrypt)
+   and the Linux kernel's kTLS (Linux 4.17 or newer). There are a few
+   limitations; see below.
+ - fMP4 (HLS) output support, generating playlists on-the-fly. Note that this
+   requires some extra metadata currently only set by Nageru (not VLC).
  - IPv4 support. Yes, Cubemap even supports (some) legacy protocols.
 
 
 HOWTO:
 
-  sudo aptitude install libprotobuf-dev protobuf-compiler
+  sudo apt install libprotobuf-dev protobuf-compiler libsystemd-dev libtomcrypt-dev
+  ./configure
   make -j4

+Notes on TLS support:
+
+Cubemap supports TLS on output, so that you can play video on TLS
+web sites without issues with mixed content. TLS on input streams is
+not (yet) supported.
+
+TLS requires kTLS for both send and receive, ie., Linux >= 4.17 with CONFIG_TLS
+enabled. Only cipher suites supported by kTLS is supposed, ie., AES-128-GCM
+(if no such cipher suite is available, the connection will be aborted). If the
+server is restarted before the key exchange for a connection is completed,
+that connection will not survive the restart, unlike all other connections.
+(This is a TLSe limitation.) You can have different certificates on different
+ports (and have separate ports for TLS and non-TLS), but SNI is not yet
+supported.
