Last time I looked at BEEP it was incredibly verbose and looked painful to implement. Apparently the designers thought at XML was a good idea and the verbosity was not an issue. That was in relation to alternatives to venerable, slim and simple syslogd protocol.

I personally think that the added verbosity and complexity of BEEP would outweigh any gains that might be obtained by sending multiple results. In short I do not think resurrecting BEEP is a good idea.

If you do want to resurrect something then RDP might make sense. RDP has most of the features of TCP except for the in-order delivery feature and was intended for bulk data transfer. Currently RDP implementations are very hard to find.

Beep framing overhead looks like this. You call this incredibly verbose? Compared to HTTP?

MSG 0 1 . 52 120
[the msg contents]
END

XML shows up only briefly during channel setup, and is quite minimal:

I: MSG 0 1 . 52 115
I: Content-Type: application/beep+xml
I:
I: <start number='2'>
I: <profile uri='http://iana.org/beep/FOO' />
I: </start>
I: END

Transporting HTTP over BEEP would allow multiple, simultaneous, bi-directional HTTP requests in parallel, multiplexing use of the same TCP connection.

I don't think it will happen, but I don't think SPDY will either :-)

I can see one way SPDY happens: Google supports it on all their servers, and pushes support for it into Chrome/Chromium and, crucially, their mobile browser in Android. Throw on top of that a Google-operated caching proxy service that Android users can use (as transparently as possible, of course!) so that browsing the Internet from your mobile suddenly got 2x - 3x faster without having to upgrade to 4G or what-have-you, and I think you'll see a lot of pressure for others to support SPDY.

Meanwhile, Google laughs all the way to the bank monetizing the extensive marketing data they've collected from these proxies about what people are actually browsing on their Android phones.

Or, am I just extra cynical in the morning?

I would not describe that as cynical, but rather as an interesting strategy well in line with Google's business model

I assure you that those logs are available from many big phone companies.
