Now for E-6...
Well there is contact info on the website and in the announcement message elsewhere on APUG. I'd guess if there is interest and a few commitments to order, it could happen.
The RA-4 kit can be mixed in 1 Litre amounts, and the mixed working solutions have a shelf life of 6-8 weeks. Same with the Kodak E6 kit. Now you will need some good graduated cylinders to use them, and something to fill the concentrate bottles to remove air. In a pinch, a can of butane lighter fuel will work fine, just refrain from smoking in the area.
PS you should change your sig and change the @ to a period, works better.
RA-4 dev is three bottles, blix is two. There is more than a little difference between a large 465gm can of butane and a propane depot with a many thousands of kilos of propane. BTW, I'm pretty sure there was a BLEVE there, the photos sure showed a nice fireball.
Also, in Montréal I can get the 1 Gal. kits of RA-4 developers and the 10L kits of blix.
What I do is that I mix the developer all at once, use as much as I can in one, or two successive sessions, and try to finish what's left in my brown stoppered bottles within three weeks. Passed that, I throw it away. Not a big waste, usually.
For blix, I just mix batches of 1L at a time. The chemicals are pretty stable in concentrated form, and the measures are easy. No need to fuss with thirds of mL as would be the case with developer.
Don't know why Kodak can't make a 1L bottle of the developer available, for smaller volume users From what I understand Blix lasts much longer in the bottle then developer does.
And does Fuji do them?
We're actually lucky to be able to find low-volume colour chemicals at all. Analog colour darkroom printing is not in a position to be competitive. There's only one grade of paper left, and contrast controls are tedious and difficult (e.g. unsharp masking).
For all practical matters, shooting C-41 and printing analog is equivalent to shooting slides with a wider dynamic range. You can push/pull C-41 film a little bit more than with E6, but that's it. RA-4 can still be very aesthetically satisfying, but you have to be aware of its practical limitations.
Kodak doesn't sell RA-4 dev in a 1L bottle like it can do with PolymaxT because colour chemistry is not as simple as B&W. (From what I can see when I mix dev, the A, B, and C parts react together to form the developer. But I might be wrong; there's a change of colour along the way).
In the 1 Gal kits, you have three very small bottles which are then diluted with water to make 1 Gal (3.5L). I suppose that calibrating exactly the bottles for 1L total would be a pain.
At any rate, Kodak provides exact measurements if you want to make only 1L of developer:

And when you do the maths, 1 Gal. isn't that much. I use Unicolor drums, which requires 2oz of developers per 8x10. At 128oz per gal., it's 64 sheets. Divided by three for nailing down exposure, color balance, and errors, that's about 20 different pictures, half less if you do 11x14 prints (4oz each). Well within hobbyist limits.
Unlike B&W, colour photography requires an infrastructure that is way beyond the capabilities of any boutique manufacturer. There is a reason why only Kodak and Fuji are producing colour film, and Foma, Efke, Adox, Maco, etc do not.
