comment How to create Vector Polygons at the same amazing speeds GISCloud is able to render them?
So far, every single person that I have seen using this technique has not posted the code. IMHO, because the important part is really happening on the server and there is no "standard" for this and because choosing what each pixels means (1=sold,2=avail,etc) is so specific to your current map that this code is most likely not "generic".

Great. Have you tried it yourself?

Ah! Do not look at the JSON file, look at the other seemingly unimportant images that get passed around :) See my answer below.

comment Is it permissible to update features after the feature cursor has been released?
Yes. It is fine. The recycling cursor answer below addresses your second question :)

comment uniquely identify feature classes & compare them for equality
FindField is O(1) + COM overhead. How do I know? I worked at the GeoDatabase team for several years maintaining and extending this code. ESRI is worried that you are paying unnecessary COM marshaling price. AFAIK Object.ReferenceEquals is testing for equality of reference of the .NET wrapper, which is very different than the address of the COM object itself (which is tested by IsIdentical). Unless the ESRI shipped wrappers have been modified to use IClone::IsIdentical (they could, I do not know though), they would have different behavior.

@ScottB Oh, it goes to show my ignorance of certain .NET data structures. Going to edit my answer :)

comment How to store large amounts of text in an SDE table
Actually, this is the way to do it. @Kirk: are you worried he will run out of memory before the cursor flushes (a valid concern). You can force the flushing using the Flush method on the cursor Object. Don't do it too often, since you loose optimizations that you get by bunching your inserts and updates together.

comment Why do ArcMap.exe processes stay open after I close ArcMap?
Also, sometimes when the act of being just visible may not necessarily be enough to cause the circular reference - it may require some event to happen for that condition to manifest itself. For example, the command can be visible and everything is fine and dandy waiting for the "StartEditing" event to happen. Once that triggers, it decides to start grabbing references to other things - and there it sets up its other references which do cause the circular condition. This was a classic problem with VB extensions and even more with .NET commands because of the non-deterministic garbage collection
