On first reading it this morning I was fairly cool on Netcodes, but I've been warming to is since, both from your rationale and intuitively.
I think Doodats is preferable to Doodads, because it rolls off the tongue more crisply, it will have some meaning a global audience which has never heard of doodads. And for those who know doodads, they will get it also.
K.I.S.S.
Doodats appears to have something going for it, according to your gf and filipina friends' feedback.
OK, I'll stick my neck out and suggest incorporating it into the following combination:
Project = Netcode
Business oriented currency = Codes
Social networking focused currency = Doodats
Anyway, I'm going to let the dust settle, while keeping an eye out for any new names that appear, and wait too for any possible eureka moment to emerge.
