			== All The Pretty Colors ==

			Ok, the color issue has been resolved. Oleg and Alexandre had said multiple times to adjust phase to
			fix the colors, but I had thought that relative small values of phase adjustment should be used. I wrote an
			application (C#/WPF) that talks to some custom php scripts which allows one to quickly adjust the dcm phase of each sensor. (See below) Once this was done it took about 2 seconds to get good images on both sensors. Oleg also sent new x359 bits which fixes some slight problems causing 1 bad frame upon a sensor mux. I will release all the software at some point, but if anyone wants it sooner please email.

			== Doh!!! ==

			Important tip! When comparing images from a dual headed camera, make sure the iris's on both
			lenses are open!!!!

			Still don't fully understand phase setting, what is hitting sensor registers, etc.
			I do fully understand the php interface and other various ajaxy scripts etc.

			Weekend reading assignment is all src code. Hope to have SW done by end of next week, at least in some usable state, which I think is doable now.

			== Two heads are better... ==

			Got some results attempting dual head. Managed to switch between sensors and get imagery from both, although there seems to be some issue with color and or syncs in the images. Looking into that now. But not bad for first time. Maybe I'm not stopping the compressor correctly, or not waiting long enough between stopping and starting. It currently takes about 3 seconds to do a switch (with messed up colors, but other than that working). This is kinda slow, so I may need to find a way to speed that up.

			Using the php is pretty easy. Much nicer to have a bunch of custom scripts than to have to do everything by passing params to ccam.php. While I'd prefer a straight C interface with maybe a simple socket wrapper, I must admit that the php stuff makes it pretty easy.

			== Feet to the fire ==

			Nothing like dangerously close deadlines to speed up the learning process...

			Current plan is to have a c#/wpf dual head camera control app that also allows for science annotation...All using http, no rtp.

			Actually making good progress. Playing/reading all the php scripts.
			Got multi-threaded http image reader/display going on windows (C#, WPF). It seems
			plenty fast, and no noticeably latency: This is using a single sensor running through the 10359 in
			"Transparent" mode.

			(image request, image read, display set source, display invalidate: )
			8-9 ms (320x240) <br>
			12-14 ms (640x480) <br>
			19 - 20 ms (1296x960) but starts to clobber the UI of the app . <br>
			45 - 50 ms (2592x1936) bit of stuttering and UI getting very unresponsive. <br>

			So very very promising...need to clean up the app, better thread handling, add dual head, add camera control, etc. etc....

			== Plunging into dual head ==

			After getting a great amount of support from the elphel team,
			I managed to successfully test the 10359 board. Although only
			with one sensor module (the other I got from SCINI team didnt work, but they had mention that they thought that they had killed it (static, bad voltage, penguin attack?, who knows...).

			I'm trying to procure another sensor board today.

			But FWIW I got images easily through the 10359 using the following sequence of steps (provide by Alexandre Poltorak):
