So basically a pluggable HSM? Curious if this should be considered more similar to the Yubi HSM 2 [0] (think dedicated HSM, not very useful for anything else but very secure) or the USB Armory [1], very adaptive small arm SBC with a USB port? (for this thread option 3 - more similar to a bone stock Yubikey?)

Also curious if there are plans to support BLS signatures natively?
