In the meantime, progress on CZ2D is coming along swimmingly. The main HUD and Inventory screens are experimental, but working. The Magazine system for the guns is also working (for magazineless weapons like the single-shot hunting shotgun, you have a 24-round-capacity pouch to draw from).
The inventory system is pretty much fully working. The player has a general inventory whose capacity depends on several things, like the pockets on their clothes, the size of their backpack, even not having any weapons drawn will give you the small bonus of carrying stuff in your hands. They also have a set of specialised inventories called Pouches. Pouches only have a very limited capacity and can only hold a small range of items, but weapons and other wield-able items can draw directly from them (accessing the general inventory means stopping to refill Pouches by holding R or opening the inventory window). The player has one of each pouch automatically and cannot lose them, but their main functions is as a quick-access inventory, so can't be relied on for storing items.
I might be able to treat you all to an experimental version of CZ2D quite soon, but don't expect anything spectacular, at the moment the focus is on getting it fully functional, and the zombies are waiting until I can get my head around pathfinding.
The final part of this update is that my lovely Kindle 2 (the white on with the fancy brushed aluminium back) has died from screen failure after 2 years of loyal service. Unfortunately, as I bought mine just before the smaller 3rd-gen ones came out, the 2nd-gen has been out of production for nearly as long as mine has been giving my stuff to read. Hopefully soon I can gather enough money for the Kindle Touch 3G, which, while looking nowhere near as nice as the 2nd-gen, at least doesn't look like a toy like the 3rd-gen does, and has the benefit of a touch-screen to play around with.
I was halfway through Charles Stross' Jennifer Morgue too..
Which I highly, highly recommend, by the way.
