Hi Randell,
What do you think about the following additional requirements:

Req. 7: Data streams MUST provide fragmentation at a layer above UDP, such that IP-layer fragmentation does not occur no matter how large a message/buffer the Javascript application passes down to the Browser to be sent out.

Req. 8: The data stream transport protocol MUST NOT encode IP addresses inside its protocol fields; doing so reveals potentially private information, and leads to failure if the address is depended upon. 

Req. 9: The data stream protocol SHOULD support unbounded-length "messages" (i.e., a virtual socket stream) at the application layer, for such things as image-file-transfer; or else it MUST support at least a maximum application-layer message size of 4GB.

Req. 10: The data stream packet format/encoding MUST be such that it is impossible for a malicious Javascript to generate an application message crafted such that it could be interpreted as a native protocol over UDP - such as UPnP, RTP, SNMP, STUN, etc. 

I believe SCTP can do 7+8+9 the above if its options are chosen right, and of course TCP can.
And I'm guessing DTLS will satisfy 10 above, as would websockets-style masking.
