Hi Rob,
I guess so . Specially concerning to voltage output - where the costs will be little ( just connectors -and some driver IC at most - less than $ 2,00 .
If well planned it allows tpo use EEG without computer in real-time (coupled to a nfb device ) - but yet holding the recordings for later.
Maybe it's not advisable include already Output Devices ( for focus theidea in the EEG , and for not become expansive ) but at least , let the OUTPUT ready for connections and for people imagine devices for that !

Maybe we could let those openEEG's connections with a good documentation
allowing further biofeedback devices will be adaptable to it ( and actual ones be updated in this sense) .
-connection 1 :
let one voltage OUTPUT (after preamp and main amp -and before
ADconversion ) - for coupling to
nfb machines and to control some feedback efectors,
vco ,stimuli generators and other openEEG
( directly, without computer)
- connection 2:
let one voltage INPUT to share ADC - allowing , eg, using
three 'openEEGs' together, one goes to computer
(using channel 1) and the others connect to that first using channels
2 and 3 .

Great idea. Do these options include connecting a switching relay which
controls VCRs and video games, or sound light mind machines?
