That's a pretty good point (with layout I meant both colemak and ortholinearity (is that a word?)). I do think it's additional work to learn colemak on a standard keyboard, but I guess you could go for it if you think it would pay off. I just prefer having the same keyboard for all my computers.

Oh right

I'd like to keep the board as flat as possible, mimicking the TOTEM's case which doesn't add any height. This means I'll have 0.2 mm between the main PCB and the bottom plate, and AFAIK there is no battery that would have the correct size for this.

Thanks, great suggestion! But as it seems it would make use of less common parts (I mean parts that can't be gotten from local shops or ergo keyboard part sellers like splitkb), plus I think the batteries would be too small even compared to the 80mAh batteries used with nice!nanos.

If you don't mind around 4 hours of downtime per month (for now) I could host it for you at renn.es (contact info is there, just send us an email and we'll send you an invite to a matrix room or something). We basically have a great server with nothing on it, so having one more service running wouldn't really have any impact (we have 2-3 gigs of ram usage avg. out of 32).

EDIT: the server is in france with 6gbps down and 2 gigs up

I wasn't born back then, but it would have been the fact that search results weren't total crap like today: only reddit seems to offer decent results if you don't want sites like wikihow to come up... I wrote a more elaborate blogpost partly about it.
