[Tom] 
The main specs for the protocol are in the RFC Editor's queue and should
emerge "any day now".  Future work in the dccp group will deal with
supplying more capabilities -- things like RTP over DCCP and TLS over
DCCP.  We'll also be investigating new congestion control techniques (in
cooperation with the iccrg (Internet Congestion Control Research Group)
that handle some of the idiosyncrasies of specific applications, like
interactive media streams.

[Tom] 
There's no other IETF protocol that directly provides the capabilities
that DCCP does, as far as I know.

> 3. If DCCP uses already somewhere today?
[Tom] 
There are implementations available for Linux and NetBSD.  They are not
completely up-to-date yet, but they do provide significant functionality
and are being updated continuously.

[Tom] 
Sorry, can't understand this.

> 5. What means "TCP-friendly"?
[Tom] 
If a flow not using TCP congestion control will receive roughly equal
throughput as a TCP flow operating in the same conditions, then that
flow is said to be "TCP-Friendly".
