Tying EVA/Jetpack to Tech Nodes?

[Headhunter09]

Does anyone know if it is possible to disable EVA and EVA Jetpacks (by any means)?

The aim here is to require a tech node to be unlocked before you can EVA. Does anybody know of an existing plugin that does this?

I've searched around but found nothing. At this point even a nod in the right direction would be a blessing. Thanks!

Check BTSM, not sure if that removes the jetpack or just zeroes the fuel though.

Thanks! For posterity:

BTSM does it by having a flight manager do a check every Update. If the current vessel is an EVA Kerbal, it checks ResearchAndDevelopment.GetTechnologyState() for the appropriate node and then manually explodes the vessel root part.

For thrusters, it subscribes to the EVA start and end events and zeroes out the fuel if the required node is not unlocked.

Every frame it also manually removes the Renderers for helmet and thrusters, respectively.
